Answer:

2. 7 + 4

3. 21 - 27

4. 8 - 28

Step-by-step explanation:

2. 1 (7+4) = 1×7 + 1×4 = 7 + 4

3. 3 (7-9) = 3×7 - 3×9 = 21 - 27

4. 4 (2-7) = 4×2 - 4×7 = 8 - 28

hope this helps :)

Answer:

Answer

Find out the how many minutes are spent preparing.

To proof

As given

A recipe takes 90 minutes to make.

25 percent of the time is spent preparing the ingredients.

25% is written in the decimal form

= 0.25

Time spent in preparing = 0.25 × 90

= 22.5 minutes

Therefore the 22.5 minutes are spent preparing the ingredients.

Hence proved

Which line has a slope of 0.625, and which line has a slope of 1.6?

kirill115 [55]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b; where y and x are variables, b is the y intercept (i.e. value of y when x is zero), m is the slope of the line.

The slope of a line passing through the points $(x_1,y_1)\ and\ (x_2,y_2)\ is:$

$m=\frac{y_2-y_1}{x_2-x_1}$

Let the point where the two lines intersect be the origin (0, 0).

Line 1 passes through (0, 0) and (8, 5). Hence:

slope of line 1 = $\frac{y_2-y_1}{x_2-x_1}=\frac{5-0}{8-0} =0.625$

Line 2 passes through (0, 0) and (5, 8). Hence:

slope of line 2 = $\frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{5-0} =1.6$

2(3b-1)=40 Simplify.

timofeeve [1]

Answer:b=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(3b−1)=40

(2)(3b)+(2)(−1)=40(Distribute)

6b+−2=40

6b−2=40

Step 2: Add 2 to both sides.

6b−2+2=40+2

6b=42

Step 3: Divide both sides by 6.

6b/6=42/6

b=7
