do what's inside the parenthasees first
start over
parenthasees
exponents
multiplication and division yes 78 times 91
addition and subtraction so
78 times 91 is first
78 times 91=7098
addition
(7098+42)^2
(7140)^2
restart
parentasees simplified
exponents
7140^2=50,979,600
Answer:
x = 13
Step-by-step explanation:
x and 167 are a linear pair, x plus 167 will equal 180
x + 167 = 180
x = 180 - 167
x = 13
To check: x + x + 167 + 167 = 360
x = 13
13 + 13 + 167 + 167 = 360
26 + 167 + 167 = 360
26 + 334 = 360
360 = 360

Use deAmos deAmos is cool and it works
Step-by-step explanation:
90 nickels = 5*90=450=450/100=$4.5,
16 dimes=16*10=160=160/100=$1.6
16 quarters = 25*16=400=400/100=$4
7 fifty-cent pieces = 7*50=350=350/100=$3.5
Total dollars = 4.5+1.6+4+3.5=$13.6
Explanation : Hope it helps you Kenzee..
just correct me if I'm wrong..
74 = 20(2.5) + 20(x)
74 = 50 + 20x
74-50 = 20x
24 = 20x
24/20 = x
1.2 = x
x = 1.2 yards of red felt
