Answer:
a)102 b)76.5%
Step-by-step explanation:
20 percent of 85 is 17 so you would add the two to get 102. For the second one, 65 is x percent of 85, of means multiply so 85x/100=65 85x=6500
6500/85= approximately 76.4705, rounding this to the nearest hundredth to get 76.50

1 Thomas uses a graphing calculator to solve the following word problem. Two shirts and five pairs of pants cost $150. Three shirts and four pairs of pants cost $190. Find the cost of a shirt. Select the statements that describe the steps that Thomas can use to solve the problem using his graphing c A Let x equal the cost of a shirt and y equal the cost of a pair of pants. B Solve each equation for y. c Solve each equation for r. D The solution is the point where the lines intersect. E The solutions are the points where the lines intersect the y-axis.
Answer:
The correct options are;
A. Let x equal the cost of a shirt and y equal the cost of a pair pants
B. Solve each equation for y
D. The solution is the point where the lines intersect
Step-by-step explanation:
The cost of two shirts and five pants = $150
Three shirts and four pairs of pants = $190
Let x = The cost of a shirt and y = the cost of a pair of pants
We have;
2·x + 5·y = 150
3·x + 4·y = 190
We solve each equation for y, to get;
For the first equation, we have;
2·x + 5·y = 150
5·y = 150 - 2·x
y = 150/5 - 2/5·x = 30 - 2/5·x
y = 30 - 2/5·x
For the second equation, we have;
3·x + 4·y = 190
4·y = 190 - 3·x
y = 190/4 - 3/4·x = 47.5 - 3/4·x
y = 47.5 - 3/4·x
The solution is the point where the two lines intersect, which is given as follows;
y = y
47.5 - 3/4·x = 30 - 2/5·x
17.5 = 3/4·x - 2/5·x = 7/20·x
x = 20/7 × 17.5 = 50
The cost of a shirt = x = $50
The cost of a pair of pant = y = 30 - 2/5·x = 30 - 2/5 × 50 = 10
The cost of a pair of pant = $10.
Decide whether the statement is true or false. If false, rewrite the
right-hand side of the equation so the statement is true.
1. 4(2 + 7)? 4(2) +7
Answer:
It's False
4(2 + 7) = 4(2) + 4(7) = 36
Step-by-step explanation:
4(2 + 7) = 36
4(2) +7 = 15
The converse of “If x=3, then 5x=15” is “If x≠3, then 5x≠15
True or false
Answer:
True
Step-by-step explanation:
This is true beacuse if x=3, then you would get this answer: 5(3)=15
But, if x does not equal 3 you wouldn't get 15. Instead, you'd get a differet number.
Si al triple del cuadrado de un número se le suma siete veces el mismo número se obtiene por resultado 10. ¿Cuál es ese número?
Answer:
The value of the number is either 1 or -10/3
Step-by-step explanation:
If the same number is added to triple the square of a number seven times, the result is 10. What is that number?
Let the number = x
Therefore, we have;
3·x² + 7·x = 10
Therefore, we have;
3·x² + 7·x - 10 = 0
Dividing by 3 gives;
x² + 7/3·x - 10/3 = 0
Factorizing gives;
(x - 1)·(x + 10/3) = 0
x = 1 or -10/3
The number is either 1 or -10/3.

Answer:
Not a function because some x values have multiple y values
Step-by-step explanation:
The meaning of a function is that an x value can only have on y value. If we were to pass a vertical line through this graph, we would find that about 2 points would be hit every time. This tells us that the x values have multiple y values and it's not a function.

Find the values of x and y.
A. x = 129, y = 51
B. x = 51, y = 129
C. x = 66, y = 17
D. x = 17, y = 66
Answer:
C
Step-by-step explanation:
129=2x-3
132=2x
x=66
129+3y=180
180-129=3y
51=3y
y=17

in what quadrant can you find the point (-5,4)
Answer:
Quadrant II
General Formulas and Concepts:
The top right square of the Cartesian Plane is the First Quadrant.
The top left square of the Cartesian Plane is the Second Quadrant.
The bottom left square of the Cartesian Plane is the Third Quadrant.
The bottom right square of the Cartesian Plane is the Fourth Quadrant.
Read the Cartesian Plane counterclockwise starting from the top right.
Step-by-step explanation:
Step 1: Define
(-5, 4)
x = -5
y = 4
Step 2: Find
We know since x = -5, our point is either going to be in Quadrant II or IIISince y is positive (4), it will go up, meaning that the point will be in Quadrant IIUse absolute value to find the distance between −112 and 114 .

recipe says that 2 cups of rice will serve 6 people. Determine how many people can be served with 10 cups of rice and how many cups of rice you need to serve 45 people. Cups of Rice i need answers
Answer:
10 cups for 30 people
15 cups for 45 people
Step-by-step explanation:
Since this is a ratio problem and we only need to find the value of one variable (how many people can be served) then we can use the Rule of Three to solve this problem like so...
2 cups <========> 6 people
10 cups <========> x people
(10*6) / 2 = x ... cross multiply the two available numbers and divide by the third
30 people = x
We can now see that 10 cups of rice can feed 30 people ... Now we can use the same process to find the number of cups needed for 45 people.
2 cups <========> 6 people
x cups <========> 45 people
(45*2) / 6 = x
15 cups = x
