Y-3=2(x+1) please please help

Ivahew [28]

Answer:

y=2x+5

Step-by-step explanation:

distribute 2 to x and 1, do this by multiplying each.

you should get y-3=2x+2.

then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.

you then get the answer, y=2x+5.

What is the length of CD? in this diagram ABC ~ EDC

eduard

Answer & Step-by-step explanation:

These triangles are similar. This means that they are going to have the same ratios within their different sides.

AC and CE already have measurements so we are going to find the ratio between them. We can do this by dividing 21 by 7.

21 / 7 = 3

So, since the ratio between AC and CE is 3, then the rest of the triangle has a ratio of 3 with the other triangle.

So, let's set up an equation so we can find the value of x.

21/7 = (20 - x)/x

Cross multiply.

21x = 140 - 7x

Add 7x to both sides of the equation.

28x = 140

Divide 28 from 140.

x = 5

Now that we have the value of x, then we can find the measurement of CD.

The measurement of CD is 5.

Find 10-3. Write the subtraction fact two ways.

love history [14]

This is a problem of fact families, but what is fact families? Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by writing the subtraction fact two ways. So we have:

 $10-3$

First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:

Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

So I want to take away 3 triangles, then by taking away 3 what is left? Well the answer is 7:

Δ Δ Δ Δ Δ
Δ Δ

That is, if we subtract 3 from 10 then the result is:

$10-3=7$

Second way. In this subtraction we take the same 10 triangles:

Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ

Now I want to take away 7 triangles, then by taking away 7 what is left is 3:

Δ Δ Δ

That is, if we subtract 7 from 10 then the result is:

$10-7=3$
