Answer:
a
Step-by-step explanation:
given
3(x - 2) < 18 ← distribute the left side
3x - 6 < 18 ( add 6 to both sides )
3x < 24 ( divide both sides by 3 )
x < 8 → a
Answer:
19
Step-by-step explanation:
38 words in 2 minutes, so one minute would equal 38 divided by 2
I'll do the 2d problem to show you how it's done; always remember your order of operations - PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction).
6h - (9 - 3h) = 6 - 3(h + 2) Distribute what's in front of the parenthesis to the inside
6h - 9 + 3h = 6 - 3h - 6 combine like-terms on both sides
9h - 9 = - 3h Isolate the variable onto one side
12h = 9 Divide by 12 to get the variable alone
h = 9/12
H=10+4x
flat rate of ten plus how ever many hours you've had it times 4
Answer:
10 x² - 4x
Step-by-step explanation:
Area trapezoid = 1/2 ( (b1+b1)h)
1/2( 2x * 10x - 4)
1/2(20x² - 8x)
10x² - 4x
