Answer:
C. 60
Step-by-step explanation:
x + 10 = 70
Subtract 10 from both sides
x + 10 - 10 = 70 -10
Simplifying
x = 60
Answer:
the lowest common multiple of the above numbers is 1800
Step-by-step explanation:
list all multiples of the given numbers and look which number is common in both numbers and find the lowest one
Ok, covert the equation to y-intercept form then create a reciprocal of the slope which would give you 1/2 as your slope. m=1/2
A.
this is assuming it grows by 20% of the houses it has at that time (compound interest)
A(x)=30(1.2)ˣ⁻¹ or A(x)=25(1.2)ˣ
B(x)=3(x-1)+45 or B(x)=3x+42
B.
A(5)=62.28 or about 62 homes
B(5)=60
C.
this is tricky so I think it should have been only 20% of 30
start over
A.
20% of 30=6
A(x)=6(x-1)+30 or A(x)=6x+24
B(x)=3(x-1)+45 or B(x)=3x+42
B.
A(5)=54 homes
B(5)=60
C.
6x+24=3x+42
minus 3x
3x+24=42
minus 24 both sides
3x=18
divide by 3
x=6
after 6 years
both will have 63 homes
Lanthanides are in period 6 and actinides are in period 7. They are at the down part of the page so that the periodic table can fit on the page.
