Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

+15 +15

3m = 105

/3 /3

m = 35

To check the work just insert 35 for m:

2(35) + 35 -15 = 90

70 + 35 -15 = 90

105 - 15 = 90

90 = 90

Solution -9-8(1+4h)= -17

geniusboy [140]

Step 1. Add 9 to both sides

 $-8(1+4h)=-17+9$

Step 2. Simplify $-17+9$ to $-8$

$-8(1+4h)=-8$

Step 3. Divide both sides by $-8$

$1+4h=1$

Step 4. Cancel 1 on both sides

$4h=0$
Step 5. Divide both sides by 4

$h=0$

Done! :) Hope this helps! :)

To check $-9-8(1+4h)=-17$ follow these steps below:

Step 1. Let h = 0

$-9-8*(1+4*0)=-17$

Step 2. Simplify 4 * 0 to 0

$-9-8*(1+0)=-17$

Step 3. Simplify 1 + 0 to 1

$-9-8*1=-17$

Step 4. Simplify 8 * 1 to 8

$-9-8=-17$

Step 5. Simplify -9 -8 to -17

 $-17=-17$

Done! :)

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing ounces. Rob

Blababa [14]

Question:

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing 7 1/4 ounces. Robin’s basket contains 6 apples, each weighing 6 1/2 ounces. Whose basket is heavier and by how much?

Answer:

Robin’s basket is heavier than Ted’s basket by 2.75 ounces

Step-by-step explanation:

Given:

Ted’s basket contains = 5 apples

Weight of each apple in Ted’s basket = 7 1/4 ounces

Robin’s basket contains = 6 apples

Weight of each apple in Robin’s basket = 6 1/2 ounces

To Find:

Whose basket is heavier and by how much?

Solution:

Step 1: Finding the weight of Ted’s basket

Weight of Ted’s basket = Number of apple in the basket X Weight of each apple

Weight of Ted’s basket = $5 \times 7\frac{1}{4}$

Weight of Ted’s basket = $5 \times \frac{29}{4}$

Weight of Ted’s basket = $\frac{145}{4}$

Weight of Ted’s basket = 36.25 --------------------------------(1)

Step 2: Finding the weight of Robin’s basket

Weight of Robin’s basket = Number of apple in the basket X Weight of each apple

Weight of Robin’s basket = $6 \times 6\frac{1}{2}$

Weight of Robin’s basket = $6 \times \frac{13}{2}$

Weight of Robin’s basket = $\frac{78}{2}$

Weight of Robin’s basket = 39 ounces--------------------------(2)

Comparing equation (1) and (2)

39 - 36.25 = 2.75 ounces

Weight of Robin’s basket > Weight of Ted’s basket

PLEASE ANSWER ITS DUE SO SOON

geniusboy [140]

the line is negative because it goes down as you move right

slope = rise/run = 4/2 = 2

y = 2x+b

use a point on the line - I picked (-4, 3)

3 = 2(-4)+b

3 = -8+b

11 = b
