Answer:
Equation: 100 = 2x + 4y
There are 9 4 points problems
Step-by-step explanation:
In this case, we know that we have a test that in total, we must sum 100 points. This could be with question of 2 points or questions of 4 points.
We do not know exactly how many questions of 2 or 4 point are, but we can write an equation that could give us an idea.
Let's call "x" the number of questions worth 2 points.
Let's call "y" the number of questions worth 4 points.
All together must give 100 points, therefore, the logic equation to do this is:
100 = 2x + 4yNow, for the second part of this problem, we want to know how many 4 points problems would be in the test if we have 32 questions of 2 points. For that, we use the above equation, and solve for y:
100 = 2(32) + 4y
100 = 64 + 4y
100 - 64 = 4y
36 = 4y
y = 9Hope this helps

Step-by-step explanation:
option B , x = 6 is the correct answer of this question .
Hope this will be helpful to you plz mark my answer as brainlist ..
Answer:
b. x = 6
Step-by-step explanation:
Solve for x :
10(x + 2) - 15 = 65
To solve this we need to isolate x :
Distribute the ten to both numbers within the parenthesis :
(10(x) + 10(2)) - 15 = 65
10x + 20 - 15 = 65
Order of operations :
10x + 5 = 65
Subtract 5 from both sides :
10x = 60
Divide 10 by both sides :
x = 6

Step-by-step explanation:
You already have 700 words typed out, which means you have 5500-700 = 4800 words left to type. If you are typing at a rate of 20 words per minute, you will need 4800/20 = 240 more minutes to finish typing your essay. That is 240/60 hours, or 4 hours.

Find the slope of the line passing through the points and ( -6, -5 ) and (4, 4)
Answer:
Slope: 9/10
Step-by-step explanation:
We need to find the slope of the line that passes through the coordinates given.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1
Plug in your coordinates and solve:
m = 4-(-5)/4-(-6)
m = 4+5/4+6
m = 9/10
Since we can't simplify further, the slope of the line would be 9/10.

2t ² + 5t - 63 Factor the trinomial
Answer:
(2t-9)(t+7)
Step-by-step explanation:
2t^2 + 5t - 63
9x14 = 63
14 - 9 = 5
2t^2+14t - 9t -63
2t ( t+7) -9 (t+7)
(2t-9)(t+7)
Hope this helps!! :))
Step-by-step explanation:
2 t ² + 5t - 63 = 0
2 t² + 14 t. - 9 t -63 = 0
2t ( t + 7) - 9 ( t + 7) = 0
(2t - 9) ( t + 7 ) = 0
t = - 7 , 9 / 2

Susanne has no money. In order to buy her sister a gift, she borrowed $15 from her mom. When her birthday came, she received $45 dollars. If she repays her mom, how much money will she have?
Answer:
$30
