Evaluate 7xy ÷ w + 4z when w = 10,x = 2,y = 5, and z = 9

1 answer:

4 0

First,, we need to insert the numbers in before we can start solving. This will change the expression to the following:
7(2)(5) ÷ 10 + 4(9)
We are first going to begin solving this by calculating the expression 7 × 2 × 5 ÷ 10. We can start this solving this by multiplying 2 by 5.
7 × 10 ÷ 10
Any expression divided by itself equals 1,, so the expression changes to:
7 × 1
Any expression multiplied by 1 remains the same,, so add 7 back into the equation.
7 + 4 × 9
Multiply the numbers together.
7 + 36
Lastly,, add the numbers together to find your final answer.

12 less than the quotient of a number and seven is -2 find the number

kiruha [24]

A quotient is the result of a division.
Let the unknown number be x.

We translate the problem into an equation, piece by piece.

"quotient of a number and seven" ----> x/7

"12 less than the quotient of a number and seven" ----> x/7 - 12

The word "is" means "="
x/7 - 12 =

All the above is -2, so it equals -2.

x/7 - 12 = -2

$\dfrac{x}{7} - 12 = -2$

First, add 12 to both sides and simplify.

 $\dfrac{x}{7} - 12 + 12 = -2 + 12$


 $\dfrac{x}{7} = 10$ 

Next, multiply both sides by 7.

$\dfrac{x}{7} \times 7 = 10 \times 7$

$x = 70$

Answer: The number is 70.

There are 127 lbs of fruits in the store: apples, oranges, and peaches. There are four times as many apples as there are peaches

Pepsi [2]

Let
x------> amount of pounds of apples
y------> amount of pounds of oranges
z-----> amount of pounds of peaches

we know that
x+y+z=127------> equation 1
x=4z-----> equation 2
y=7+z----> equation 3

substitute equation 2 and equation 3 in equation 1
x+y+z=127----> (4z)+(7+z)+z=127---> 6z=127-7---> 6z=120----> z=20 lb
x=4z---> x=4*20----> x=80 lb
y=7+z----> y=7+20---> y=27 lb

amount of pounds of apples----> 80 lb
amount of pounds of oranges----> 27 lb
amount of pounds of peaches---> 20 lb
