Answer:

<u><em>114 - 15 = 99</em></u>

Step-by-step explanation:

<em>A "number" can be used as x since we don't know what it is at first- since it'd be x + 15 = 114 you can just do 114 - 15 to get the answer to x which is 99:)</em>

To make concrete it take 8 parts crushed gravel, 7 parts water and 5 parts cement mix. A worker needs to make 220 kg of concrete
Romashka-Z-Leto [24]

A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

Total number of parts in every load = 8 + 7 + 5 = 20 parts

If total load = 220 kg, then       20 parts = 220 kg

Divide each side by  20 :             1 part = 11 kg

gravel   = 8 parts = 8 x 11 kg = <em>88 kg</em>
water    = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>

<u>Check:</u>    88 + 77 + 55 = 220         yay !

A line passes through (-2, 3) and has a slope of 0.2. Write an equation of the line.
mars1129 [50]

Answer:

y = 0.2x + 3.4

Step-by-step explanation:

Slope intercept form of line is

y = mx + c

where

m = slope

c is y intercept

given that slope is 0.2 thus, m = 0.2

now equation of line

y = 0.2x + c

now we substitute value of x and y ( (-2, 3) in this equation as given that the given point passes through the line

3 = 0.2*-2 + c

3 = -0.4 + c

c = 3+0.4 = 3.4

put c = 3.4 in equation

y = 0.2x + c

y = 0.2x + 3.4

Thus,

third option , y = 0.2x + 3.4 is the correct answer
