First thing you do is make both sides of the equation fractions which would make it

15/100 + 44/100 = x/20 + 44/100

Then you’d cancel out the 44/100 since there are one of those on each side of the equation. That would leave you at

15/100 = x/20

You then need to get common denominators. 20*5=100 would give you a common denominator of 100, and anything you do to the denominator you do to the numerator so you’d also multiply x by 5 (5x):

15/100 = 5x/100

Then cancel out the 100 since there is a 100 as a denominator on both sides of the equation

15 = 5x

For there you divide both sides by 5 to get x by itself (15/5=3 and 5x/5=x) which would leave you with

3 = x

I’m sry if this didn’t help I’m not great at explaining math equations

In 2018, the number of students at The Villages High School was 975 and is increasing at a rate of 2.5% per year. Write and use

avanturin [10]

Answer:

$A(t)=975(1.025)^t$

In 2025,the number of students at the villages high school=1159

Step-by-step explanation:

We are given that in 2018

Number of students at the villages high school=975

Increasing rate,r=2.5%=0.025

We have to write and use of exponential growth function to project the populating in 2025.

$A_0=975,t=0$

According to question

Number of students at the villages high School is given by

$A(t)=A_0(1+r)^t$

Substitute the values

$A(t)=975(1+0.025)^t=975(1.025)^t$

t=7

Substitute the value

Then, the number of students at the villages high school in 2025

$A(7)=975(1.025)^7=1158.96\approx 1159$

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are ( , ). The coordinates of the point that is

AURORKA [14]

Answer:

Reflection across the x-axis: (-4,2)

Reflection across the y-axis: (4,-2)

Step-by-step explanation:

Going based off of what I see, a reflection across the x axis changes "y" & the same rule applies to the y axis.

It should be an L shape.

Can a pentagon have angles that measure 95°, 67°, 105°, 95°, and 177°?

pochemuha

Answer:

No, it cannot have angles that measure 95°, 67°, 105°, 95°, and 177°.

Step-by-step explanation:

S = (n-2) * 180

A pentagon has 5 sides, so substitute n for sides (n = 5)

s = 5-2) * 180 = 540°

95° + 67° + 105° + 95° + 177° = 539°

Hope that Helps!

Answer:

Function H h(t) = -6.1 + 19t - 55

Step-by-step explanation:

Let t = 1

Function F

h(t) = 6.1t^2 + 19t - 54.4

h(1) = 6.1(1)^2 + 19(1) - 54.4

h(1) = 6.1 + 19 - 54.4

h(1) = -29.3

Function G

h(t) = -24.1t^2 + 2.8

h(1) = -24.1(1)^2 + 2.8

h(1) = -24.1 + 2.8

h(1) = -21.3

Function H

h(t) = -6.1t^2 + 19t - 55

h(1) = -6.1(1)^2 + 19(1) - 55

h(1) = -6.1 + 19 - 55

h(1) = -42.1

Function J

h(t) = -6.1t^2 + 19t + 0.99

h(t) = -6.1(1)^2 + 19(1) + 0.99

h(t) = -6.1 + 19 + 0.99

h(t) = 13.89
