Answer:

A.) 28

Step-by-step explanation:

$x-3=25$

Isolate the variable by adding three to both sides

$x-3+3=25+3\\x=28$

Using the number line, use x=25+3. Move up three points and you are on 28 =)

Answer:

Step-by-step explanation:

Multiply the number of muffins by how much baking powder is in each muffin. That's read as 6/1 × 3/8 which equals 18/8.

Distance formula

$\boxed{\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

Now

$\\ \tt\Rrightarrow AB=\sqrt{(3-3)^2+(-2-8)^2}=\sqrt{100}=10units$

$\\ \tt\Rrightarrow OK=\sqrt{(5-7)^2+(-2+2)^2}=\sqrt{4}=2units$

$\\ \tt\Rrightarrow LM=\sqrt{(-4-4)^2+(6+4)^2}=\sqrt{64+100}=\sqrt{164}\approx 13units$

$\\ \tt\Rrightarrow PC=\sqrt{(5-2)^2+(1-3)^2}=\sqrt{9+4}=\sqrt{13}=3.2units$

$\\ \tt\Rrightarrow QR=\sqrt{(-2+10)^2+(3-9)^2}=\sqrt{64+36}=\sqrt{100}=10units$

Find the integer values of x that satisfy both of these inequalities.

Shtirlitz [24]

Answer:

0, 1, 2.

Step-by-step explanation:

5 - 3x <= 7

-3x <= 2

x >= -2/3 (the inequality sign flips as we are dividing by a negative value)

4x + 1 < 13

4x < 12

x < 3.

So the integer values satisfying the inequalities are>

0, 1, 2.

The formula for the perimeter of a rectangle is P=2(l+w).

olga2289 [7]

Answer:

See below.

Step-by-step explanation:

Part A.

I'm changing the l and w to capital letters, so you don't confuse the l (small-case L) with a 1 (one).

P =2(L + W)

Since W is on the right side, switch sides to end up with W on the left side.

2(L + W) = P

Since the quantity in parentheses is being multiplied by 2, we divide both sides by 2.

L + W = P/2

L is being added to W, so we subtract L from both sides.

W = P/2 - L

Part B.

First, I switched sides to have W on the left side. Then, I divided both sides by 2. Finally, I subtracted L from both sides.
