It is a linear simple equation, lets solve it step by step:
<span>X + 3(X + 4) = 20
x + 3x + 3*4 = 20
4x + 12 = 20
4x = 20 - 12
4x = 8
x = 8/4
x = 2</span>
Answer:



Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the distance in miles
y ----> the time in hours

we have
The distance is equal to subtract 35 miles from 230 miles

The time is equal to subtract 1:30 pm from 4:30 pm

substitute in the formula of speed

<em>Isolate 3 hours</em>

<em>Isolate 195 miles</em>

Step-by-step explanation:
From the above question, we ate told that:
Becky needs to put 4 cups of flour into her bread maker to make one loaf of bread.
The size of her measuring cup = 1/3 cup
The number of 1/3 cups of flour she will need to make a loaf of bread is calculated as:
4 cups of flour ÷ 1/3 cup of flour
= 4 cups of flour × 3/1 cup of flour
= 12
