Write a linear equation to model the following situation: Frankie has $500 in her savings account at the beginning of the year.
Juli2301 [7.4K]
A linear equation can be represented by: 

y = mx + b 

Where m = slope, and b = y intercept. 

The slope is a rate of change, so our slope is $150. 
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500. 

So our equation will be: 

y = 150x + 500.

henry is mixing concrete. to make concrete he needs to mix cement, sand and gravel in the ratio 5 : 4 : 1 by weight. henry needs
MaRussiya [10]

Answer:

cement by 5 Kg

Step-by-step explanation:

add the parts of the ratio, 5 + 4 + 1 = 10 parts

Divide the quantity of concrete by 10 to find the value of one part of the ratio.

110Kg ÷ 10 = 11Kg ← value of 1 part of ratio , thus

5 parts = 5 × 11Kg = 55Kg ← cement required

4 parts = 4 × 11Kg = 44Kg  ← sand required

1 part = 11Kg ← gravel required

He requires 55Kg of concrete but only has 50Kg.

He requires 44Kg of sand and has 55Kg

He requires 11Kg of gravel and has 15Kg

Thus he is 5Kg short of cement.
