a chef prepared five chocolate tortes for a dinner party. The guest consumed 2 5/16 tortes. How many tortes are left

1 answer:

8 0

There are 5 chocolate tortes. If 2 and 5/16 are eaten then we it would be
5-2 and 5/16. We can take 16/16 out of the 5 and make it 4 16/16 to get the denominator to be the same. 4 16/16 - 2 5/16 would equal to 2 11/16

Your final answer is 2 11/16

Answer:

1) x = 4

2) a square root cannot be equal to a negative value

Step-by-step explanation:

1) add 1 to each side

2) square each side

(√2x + 1)² = 3²

2x + 1 = 9

2x = 8

x = 4

2) subtract 4 from each side

(x1,y1) is (-4,-2) and (x2,y2) is (2,4)

olga nikolaevna [1]

Answer:

y = x+2

Step-by-step explanation:

(x1,y1) is (-4,-2) and (x2,y2) is (2,4)

Slope intercept form is y = mx+b

m = slope

b = add on

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute numbers

Slope = $\frac{4-(-2)}{2-(-4)}$

Two negatives = one positive

Simplify

$Slope = \frac{4+2}{2+4}=\frac{6}{6}=1$

The slope is 1

We can substitute y, x, and the slope

4 = 2*1 + b

4 = 2+b

b = 2

Slope intercept form is y = mx+b

Answer is y = x+2

Hope this helps :)
