Mathematics
1 answer:
lapo4ka [179]3 years ago
4 0

Answer:

x=1

Step-by-step explanation:

x = -4 + 6 + (11 + 4(-3)).

First get the numbers in the parentheses

x = -4 + 6 + (11 - 12)

Since 11 - 12 = -1. We can replace (11-12) with -1

x = -4 + 6 -1

Now add and subtract

x = 1

The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.
Mars2501 [29]

Answer:

<h2>The question we need to answer is what is the perimeter of the arena</h2>

Step-by-step explanation:

The question we need to answer is what total length of plank did the farmer ordered for the arena.

to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.

given data

length L= 115 1/4 ft = 115.25ft

width W= 63 1/2 = 63.5ft

perimeter= 2L+2W

perimeter= 2(115.25)+2(63.5)

perimeter= 230.5+127

perimeter= 357.5ft

This means that the farmer ordered a total length of 357.5ft of plank

if the farmers market sold 35% of it produce and has 280 peaches remaining, how many peaches did it originally have on hand.
jonny [76]

Divide the amount left by the percentage left:

they sold 35%, so there is 65% remaining.

280 / 0.65 = 430.769

Round to 431

Now check:

431 x 0.35 = 150.85

Round to 151

431 - 151 = 280 left.

They originally had 431 peaches.
