Answer:
E. x^2 = 39 + 10x
Step-by-step explanation:
It helps to do one piece of the sentence at a time.
"A number, x, squared is 39 more than the product of 10 and x"
x
"A number, x, squared is 39 more than the product of 10 and x"
x^2 =
"A number, x, squared is 39 more than the product of 10 and x"
x^2 = 39 +
"A number, x, squared is 39 more than the product of 10 and x"
x^2 = 39 + 10x
Answer: E. x^2 = 39 + 10x
Ok so the solution which greenrune will (hopefully) correct
total is 1.5
p+r=1.5
rule is 1 more than pencil
r=1+p
sub 1+p for r
p+1+p=1.5
2p+1=1.5
minus 1 from both sides
2p=0.5
divide both sides by 2
p=0.25
pencil=$0.25
-(-2-5x)+(-2)=18
2+5x-2=18
5x=18
x=18/5=3.6
I assume that you meant RS and ST are segments of RT. If that is true then:
RS+ST=RT, using the values for these given...
8y+4+4y+8=36 combine like terms on left side
12y+12=36 subtract 12 from both sides
12y=24 divide both sides by 12
y=2
Algebra is Faster And Better Than “Basic” Math
Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
