what is the value of x in the equation 1.5 x+9.1 -2.4=-2.4
Answer:
X = -9.1
Step-by-step explanation:
Add 9.1 and -2.4 together to get
x + 6.7 = -2.4
subtract 6.7 from both sides to get
x = -9.1

What is 71,000,000 converted to scientific notation?
A. 71 x 100,000
B. 7.1 x 100,000
C. 7.1 x 10-7
D. 7.1 x 107
Answer:
7.1 × 10 7
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer: D) [tex]7.1 \times 10^7[/tex]
Explanation:
Place the decimal point between the first two digits of the given number. Erase everything after the '1'. So we have 7.1
To get back to 71,000,000 we would need to move the decimal point 7 spaces to the right
So that's why [tex]7.1 \times 10^7 = 71,000,000[/tex]
If the exponent was -7, then we would move the decimal point 7 spaces to the left.
Subtract 4x3 + 3 from 6x3 – 5x – 7.

Answer:
1002 - 712984 =711 982 - 4763987= 405 2005 - ______= 970 610 x 0.00230782703 = 2240.
250 x 1000 = 250000
2155050 x 4 = 8620 200 x 0.00464026356 = 40000
Step-by-step explanation:
a) i) 1002 - ______ =711 982
= 1002- x = 711982
= 1002 - (-711982) = x
= 712984
ii) 711 982 - _______= 405 2005
711982 - x = 4052005
x = 711982 -(- 4052005)
x = 4763987
iii) 970 610 x ____= 2240
2240 ÷ 970610 = 0.00230782703
iv) ______ x 1000 = 250000
= 250000 ÷ 1000
= 250
v) _______ x 4 = 8620 200
8620200 ÷ 4 = 2155050
vi) 8620 200 x _______ = 40000
= 40000 ÷ 8620200
= 0.00464026356
b) ¿Qué NUMERO DIVIDIDO ENTRE 2 ES IGUAL A 8642?
x ÷ 2 = 8642
x = 8642 × 2
x = 17284
c) ¿Qué NUMERO DIVIDIDO ENTRE 3 ES IGUAL A 8643?
x ÷ 3 = 8643
x = 8643× 3
x = 25929
d) ¿Qué NUMERO DIVIDIDO ENTRE 5 ES IGUAL A 9640?
x ÷ 5 = 9640
= 9640 × 5
= 48200
e) ¿Qué NUMERO DIVIDIDO ENTRE10 ES IGUAL A 6420?
= x ÷ 5 = 6420
= x = 6420 × 5
= x = 32100
f) ¿Qué NUMERO DIVIDIDO ENTRE 20 ES IGUAL A 2000?
= x ÷ 20 = 2000
= x = 2000 × 20
x = 40000
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse.
Which is an equivalent equation solved for y?
Answer:
y = a ÷ (πx)
Step-by-step explanation:
An equivalent equation solved for y is:
y = a/πx
What is an equation?An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.
The formula a = xy, where x and y are the halved lengths of the ellipse's biggest and smallest diameters, may be used to calculate the area, a, of an ellipse.
Starting from the formula a = πxy, we can rearrange it to solve for y:
a = πxy
Dividing both sides by πx, we get:
a/πx = y
y = a/πx
Therefore, an equivalent equation solved for y is:
y = a/πx.

Bailey has 45 minutes to exercise. It takes Bailey 3 minutes to jog around the track and 5 minutes to stretch. She jogs 6 laps around the track and stretches 2 times. Write and evaluate an algebraic expression to find the amount of time Bailey has left. Use j for the number of laps she jogs and s for the number of times she stretches.
Answer:
a) Time left = [45 - (3j + 5s)] minutes
b) 17 minutes
Step-by-step explanation:
a) Using j for the number of laps she jogs and s for the number of times she stretches. Since Bailey has a total of 45 minutes to complete his exercise, then;
Time left = [45 - (3j + 5s)] minutes
If she jogs 6 laps and stretches 2 times , then;
Time left = [45 - (3j + 5s)]
b) Where j = 6 and s = 2,
Time left = 45 - (3(6) + 5(2))
= 45 - (18 + 10)
= 45 - 28
= 17
Amount of time Bailey has left is 17 minutes.

Jake's mom buys pizza for him every time he completes 15 Imagine Math Lessons. Brandon's mom buys cookies for him every time he completes 9 Imagine Math Lessons. How many lessons will they have completed when they earn pizza and cookies at the same time?
Answer:
45 lessons
Step-by-step explanation:
Here, we want to know the number of lessons that both of them would have completed when they earn pizza and cookies at the same time
From the question, we are told that they earn cookies and pizza when they complete 9 and 15 lessons respectively.
So to know the number of lessons completed, we need to find the lowest common multiple of the number of cookies and the numbers of pizza
That will be lowest common multiple of 9 and 15

Two pounds of peaches cost $450, 5 pounds cost $11.25, and 10 pounds cost $22.50 Show that the relationship between the number of pounds of peaches and the cost is a proportional relationship. Then write an equation for the relationship
The equation needs to be written in y=kx format using no spaces and no capital letters.
Answer:
y=2.25x
Step-by-step explanation:
4.50 ÷ 2 = 2.25 per pound
11.25 ÷ 5 = 2.25 per pound
22.50 ÷ 10 = 2.25 per pound
Proportional relationship as each pound cost $2.25, and will increase accordingly per pound.
constant of proportionality: 2.25
pounds: x
cost: y
y = kx
y = 2.25x
Answer:
Step-by-step explanation:
Y=2.25
Because 4.50/2 = 2.25
11.25/5 = 2.25
22.50/10 = 2.25

If f left parenthesis x right parenthesis equals 2 x minus 4 and g left parenthesis x right parenthesis equals negative 5 x plus 6, then what is f(g(2))?
The value of the function f(g(2)) is: f(g(2)) = -12
Here,
To find the value of f(g(2)),
we first need to find the value of g(2), and then use that result as the input for the function f.
Given:
f(x) = 2x - 4
g(x) = -5x + 6
Step 1: Find g(2)
g(2) = -5(2) + 6
g(2) = -10 + 6
g(2) = -4
Step 2: Use the result g(2) as the input for f(x)
f(g(2)) = f(-4)
f(x) = 2x - 4
f(-4) = 2(-4) - 4
f(-4) = -8 - 4
f(-4) = -12
Therefore, f(g(2)) = -12.

Pat rents a car. The car costs $30 per day with an additional charge of $0.10 per mile. He rented it for 7 days and drove 350 miles. What is the cost for renting the car? Write an equation and solve.
Answer:
245
Step-by-step explanation:
30 times 7 is 210 and 350 times 19 cents is 35
Answer:
The equation is y = 30d + 0.10m. The cost is $245.
Step-by-step explanation:
Plug in the values for the equation. The equation will become y = 30(7) + 0.10(350). Solve to get y = 210 + 35. This equals y = 245.
Pat's chickens lay between 18 and 25 eggs per week. Pat eats 2 eggs per day and feeds the remaining
eggs to his dogs.
Complete the inequality which best describes the number of eggs (E) Pat's dogs eat per week.
Answer:
E = 16 ≤ x ≤ 23
Step-by-step explanation:
Number of eggs laid per week = between 18 and 25
Let x = exact number of eggs laid
Using inequality :
18 ≤ x ≤ 25
Number of eggs Pat eats = 2
18 - 2 ≤ x ≤ 25 - 2
Eggs left after pat eats 2 of the eggs :
16 ≤ x ≤ 23
Hence,
Eggs eaten by pat's dogs :
E = 16 ≤ x ≤ 23
