Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64
Answer:
x = 20
Step-by-step explanation:
angle m<3 + angle m<5 = 180° because these angles are supplementary
5x + 10 + 3x + 10 = 180° add like terms
8x + 20 = 180
8x = 160 divide both sides by 8
x = 20
1 dollar is to 8
1:8
so 5 dozen
1 dozen=12
5 dozen=12 times 5=60
1:8 and x:60
1/8=x/60
multiply both sides by 60
60/8=x
30/4=15/2=7.5=x
$7.50 is how much you pay
Answer:9.07 > 9.008
Step-by-step explanation:
Because I know bic
Please enclose fractions such as 8/7 inside parentheses:
<span>(8/7)x^3+x^4+6x+1
Next, arrange these four terms in order of power of x:
</span>x^4 + (8/7)x^3+ 6x+1 This is the standard form you wanted.
