Answer:

He planted 44 fields do corn, and 22 each for wheat and grass.

Step-by-step explanation:

There are three subjects. If we have something that was 2x as much as wheat, and then something half as much as that, we know that the wheat and grass are equal. Then, you just need to think about how a 50 25 25 split would work out of 88.

Simplify 4848 to 1212
s−14=12s−14=12
2 Multiply both sides by 44
s−1=12×4s−1=12×4
 Simplify 12×412×4 to 4242
s−1=42s−1=42
Simplify 4242 to 22
s−1=2s−1=2
Add 11 to both sides
s=2+1s=2+1
Simplify 2+12+1 to 33
s=3s=3

What is an equation that goes through the point (-7, 10) and is perpendicular to the line -2x-4y=9

algol13

Step-by-step explanation:

m1.m2= -1

(4y = -2x -9)= (y = -1x/2 -9/4)

-1/2.m2= -1

m2 = 2

formula = y - y1 = m2 ( x - x1)

y - 10 = 2 ( x - (-7))

y - 10 = 2x + 14

y = 2x + 24

Suppose you drive a car 392 mi on a tank of gas. The tank holds 14 gallons. The number of miles traveled vaties directly with th

Serhud [2]

Preliminary Problem

Givens

Miles = m = 392 miles

Gallons = G = 14 gallons

Miles per gallon = mpg

Formula

miles = miles per gallon * number of gallons.

Solve

392 = mpg * 14 Divide by 14

392 / 14 = mpg

28 = mpg which is really quite good. Our vehicle gets 44 mpg but it's a 4 cylinder. It's meant to get that kind of milage.

Part A

Let x = the number of gallons used

Let y = the number of miles driven

y = k*x

Part B

y = k* x

k =28 mpg

11700 = 28*x

11700 /28 = x

x = 417.86

If this is incorrect please put some more facts in. The question does not seem complete.

a jacket originally sold for $45. this week it went on sale for 20% off. what is the discount and what is the sales price?

Strike441 [17]

Answer:

discount = 9

new price = 36

Step-by-step explanation:

The discount is the price times the discount percent

45 * 20%

Change to decimal form

45*.20

The new price is the original price minus the discount

45-9 = 36

Please I need step by step solution.

4vir4ik [10]

Answer:

A) 2C

Step-by-step explanation:

The relevant rule of logarithms is ...

log(x²) = 2·log(x)

We know that 64 = 8². So, ...

log(64) = log(8²) = 2·log(8)

We are given that log(8) = C, so 2·log(8) = 2C

Here, all logarithms are to the base 9. That does not change the relations shown.
