Answer:
1 3/4
Step-by-step explanation:
2/8 * 7
2/8 will simplify
Divide the top and bottom by 2
12/8 = 1/4
1/4*7
7/4
We need to change this from an improper fraction to a mixed number
4 goes into 7 once with 3 left over
1 3/4
To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like
.
Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.
X = 14328.
120 lawn mowers would cost $14,328.
Answer:
3/5, 13/20, 33/50, 51/75, 18/25
least greatest
Step-by-step explanation:
in decimal form:
.6 .65 .66 .68 .72
least greatest
So x+x^2=20
subtract 20 from both sdies
x^2+x-20=0
factor
find what 2 nmbers multiply to get -20 and add to get 1
factors of 20=2 times 2 times 5
the combos are
2 times 10
4 times 5
1 times 20
4 and 5 are 1 in diference
5-4=1
5 times 4=20
(x-4)(x+5)=0
if xy=0 then x and/or y=0
set each to zero
x-4=0
add 4
x=4
x+5=0
subtract 5
x=-5
but you want positive so this is an extranius answer so discard this
the number is 4
27.)
13x+3+22x-2 = 106°
x = 3°
28.)
5x+14+16+x = 102°
x = 12°
