1.
2(a - 1.1) = 5.8a - 1.1 = 5.8/2a - 1.1 = 2.9a = 2.9 + 1.1a = 42.
(5/2)b - 2 3/4 = 7 1/42.5b = 7 1/4 + 2 3/42.5b = 10b = 10/2.5b = 4Both a and b have same value
Answer:
Yes, a and b have the same value in the given equations.
Step-by-step explanation:
Equation 1
[tex]2(a-1.1)=5.8[/tex]
[tex]\implies 2a-2.2=5.8[/tex]
[tex]\implies 2a-2.2+2.2=5.8+2.2[/tex]
[tex]\implies 2a=8[/tex]
[tex]\implies \dfrac{2a}{2}=\dfrac{8}{2}[/tex]
[tex]\implies a=4[/tex]
Equation 2
[tex]\dfrac{5}{2}b-2\frac{3}{4}=7 \frac{1}{4}[/tex]
[tex]\implies \dfrac{5}{2}b-\dfrac{2 \times 4+3}{4}=\dfrac{7 \times 4+1}{4}[/tex]
[tex]\implies \dfrac{5}{2}b-\dfrac{11}{4}=\dfrac{29}{4}[/tex]
[tex]\implies \dfrac{5}{2}b-\dfrac{11}{4}+\dfrac{11}{4}=\dfrac{29}{4}+\dfrac{11}{4}[/tex]
[tex]\implies \dfrac{5}{2}b=\dfrac{40}{4}[/tex]
[tex]\implies \dfrac{5}{2}b=10[/tex]
[tex]\implies 2 \cdot \dfrac{5}{2}b=2 \cdot 10[/tex]
[tex]\implies 5b=20[/tex]
[tex]\implies \dfrac{5b}{5}=\dfrac{20}{5}[/tex]
[tex]\implies b=4[/tex]
Conclusion
As a = 4 and b = 4, the two variables have the same value in the given equations.

Answer:
2 seconds
Step-by-step explanation:
The variable S represents the height off the ground, so we can substitute in the value 140 for it:
[tex]140 = 80t - 5t^{2}[/tex]
We can add [tex]5t^{2}[/tex] to both sides and subtract [tex]80t[/tex] so the equation is in standard form:
[tex]5t^{2} - 80t + 140 = 0[/tex]
Every term has five as a factor, so we may divide both sides of the equation by 5.
[tex]t^{2} - 16t + 28 =0[/tex]
To factor this, we need two numbers that multiply to 28 and sum to -16. These numbers are -14 and -2, so these are the two factors:
[tex](t-14)(t-2)=0[/tex]
We can see that when t = 14 or 2, the whole left has a value of zero, so they are the two answers.
We are asked when the rocket first is at 140m, and 2 seconds is before 14, so the answer is 2 seconds.
If a polygon had 275diagonals, how many sides
must it have?
Answer:
25 sides
Step-by-step explanation:
Number of diagonals = n(n-1)/2 where n is the number of sides.
Therefore,
n(n-1)/2 = 275
n = 25
Kaylee used her saved birthday money to set up a college savings account that earns 4.2% interest compounded weekly. If the original amount deposited was $750, how much interest will she have earned after 10 years?
Total amount of interest rounded to the nearest penny.
keeping in mind that there are 52 weeks in a year.
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$750\\ r=rate\to 4.2\%\to \frac{4.2}{100}\dotfill &0.042\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{weekly, thus fifty-two} \end{array}\dotfill &52\\ t=years\dotfill &10 \end{cases}[/tex]

What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 53p + (16p + 7p)
Fifty three times of p plus sixteen p plus seven p.
In the given expression p is the variable and plus is the operator.
We need to find the equivalent expression.
Equivalent expressions are expressions that work the same even though they look different.
53p + (16p + 7p)
76p
(53p + 16p) + 7p is also equal to 76p

OD. H

Step-by-step explanation:
come in ! think a little bit by yourself !
when x = 1, what is f(x) ?
it is f(1) = 1² = 1
what is then g(x) ?
g(1) = 1/4 × f(1) = 1/4 × 1 = 1/4
when x = 2, what is f(x) ?
f(2) = 2² = 4
what is then g(x) ?
g(2) = 1/4 × f(2) = 1/4 × 4 = 1
and equally for x = -1 and -2.
a square function always delivers positive numbers. and so does the square function multiplied by a positive constant (like for g(x)).
the only graph, where the curve is always above the x-axis (only positive results), and where the functional value for x = 1 is much smaller than 1, and the functional value for x = 2 is actually 1, is graph D.
so, D is the right answer.
At a tournament, the bowling league is providing 160 sandwiches for its members. The table shows the number of different types of sandwiches that were ordered. The ratio of turkey sandwiches to roast beef sandwiches is 5:3. Drag the numbers to complete the table.
Answer: See below
Step-by-step explanation:
The total number of ordered sandwiches is 160
The total number of Turkey Sandwiches is 80
The ratio of Turkey to Roast Beef is 5:3
So from this, 5 times of a value is 80
So 5x = 80
And x = 16
So the Roast beef sandwiches are 16×3=48
Therefore, the table is:

Answer:
Problem 1. Pikachu is level one and he wants to become level two. But he has to train, so he discovers that his attack swift gives him 1.176 points of experience. But he needs 2.352 points to reach the next level.
How many times does he have to perform the swift attack?
a)1 b)2 c)3 d)4
Problem 2. Snorlax needs to reach level 10 to enter the pokemon gym. But he is currently level 4. However, he discovers that his attack smash gives him .392 experience points and he needs 2.352 to reach level 10. How many times does he have to perform smash?
a)4 b)5 c)6 d)7
Step-by-step explanation:
This is a very easy question if you think the opposite.
1.- The opposite of multiplication is division. So with this knowledge, we can form any amount of problems we want we just need to combine the numbers with our product which is 2.352.
2.- So in the first place, let's make it easy. If we divide 2.352 in 2 then we are going to obtain. 1.176 as a product. Then we combine our product with our divisor and we can multiply them to find our initial product which was 2.352.
3.- In the second place we go more complicate, we divide 2.352 in 6 and we will obtain. .392 then we combine .392 with 6 to multiply them and we obtain back our initial objective. Can you see? it is the easiest thing to do.
4.- We then look for scenarios to put these two processes and we will find our problems.
Problem 1. Pikachu is level one and he wants to become level two. But he has to train, so he discovers that his attack swift gives him 1.176 points of experience. But he needs 2.352 points to reach the next level.

the selling price is 25.60, the cost was 16.9, that means 25.6 - 16.9 = 8.7, so the item's price has been bumped up by 8.7 bucks, which is the markup, how much is that of 25.6?
worded differently, if we take 16.9(cost) to be the 100%, what is 8.7 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 16.9 & 100\\ 8.7& x \end{array} \implies \cfrac{16.9}{8.7}~~=~~\cfrac{100}{x} \\\\\\ 16.9x=870\implies x=\cfrac{870}{16.9}\implies x\approx 51.48[/tex]

Evaluate each algebraic expression for x = 2, -3, 6, -5
The values of the expression for x = 2, -3, 6, -5 are -10, -12, 6 and -16, respectively
How to evaluate the expression?The expression is given as:
f(x) = 2x - 6
When x = -2, we have:
f(-2) = 2(-2) - 6 = -10
For other values of x, we have:
f(-3) = 2(-3) - 6 = -12
f(6) = 2(6) - 6 = 6
f(-5) = 2(-5) - 6 = -16
Hence, the values of the expression for x = 2, -3, 6, -5 are -10, -12, 6 and -16, respectively

Is 5 inches bigger than 1/3 if a foot
Answer:
Yes
Step-by-step explanation:
1 foot= 12 inches
12÷3=4
This means that 1/3 of a foot is 4 inches
5 inches is larger than 4 inches
Answer:
Yes
Step-by-step explanation:
1/3 is 0.33333333333333 foot which = 4 inches.
Formula: multiply the value in feet by the conversion factor '12'.
So, 0.33333333333333 foot = 0.33333333333333 × 12 = 4 inches.
The other value is 5 inches.
5 inches is greater than 4 inches.
