18k - 4k = -10 - 4k
18k - 4k + 4k = -10
18k = -10
k= (18/10) = (9/5) = 1.8

Answer:
32 ÷ 8 + 1 __IS NOT EQUAL TO__ 3² - 1
4² __IS NOT EQUAL TO__ 4 • 2
3(x - 4 + x) __IS EQUAL__ 3x - 4 + x
when x = 4
15 ÷ (1 + 2) ___IS NOT EQUAL TO_ 15 ÷ 1 + 2
3(x - 4 + x) __IS NOT EQUAL TO__ 3x - 4 + x
when x = 2
Answer:
below.
Step-by-step explanation:
408 = 2*2*2*3*17
1032 = 2*2*2*3*43
So the HCF is 2*2*2*3 = 24
24 = 2/1032 + p/408
24 - 2/1032 = p/408
p = (24 - 2/1032) * 408
p = 9791.21 to nearest hundredth.
Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
