Answer:
D.
Step-by-step explanation:
(4 x 8) + (4 x 3)=44
4 x (8 + 3)=44
Solve for n by simplifying both sides of the equation, then isolating the variables.
n=54
Hope I helped
Remember to include the positive and negative roots
(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)
x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2
x=2 and 4/7 or -2
Answer:
[6.5,-7.25]
Step-by-step explanation:
Given the partitioning ratio as 3:1
#Find the length of the x-coordinate and multiply by the ratio:
x length=9--1=10
=>
#We subtract 2.5 from the x-max to get the point=9-2.5=6.5
#Find the length of the y-coordinate and multiply by the ratio:
x length=-9--2=-7
=>
#We subtract -1.75 from the y-max to get the point=-9--1.75=-7.25
Hence, the coordinates that partitions the segment into a ratio of 3 to 1 is [6.5,-7.25]
Step-by-step explanation:
Take John's sister's age as "x"
So, so twice his sister's age means = 2x
And 5 years more, means = 2x + 5
So finally John's age = 2x + 5
