Answer: 300
Step-by-step explanation: 70days is 10 weeks
"5 times a sum of 12 and a number is 80" translates to the next equasion:
5 x (12+a) = 80
Now we just have to solve it to find the value of a.
The unknown number is 4.
D is the right answer.
Answer:
45
Step-by-step explanation:
If two lines are parallel and cut by a transversal, corresponding angles are congruent. Angle GEB and angle EFD are corresponding so they are congruent so you can set them equal to each other and solve.
2x - 30 = x + 15 (add 30 to both sides, subtract x from both sides)
X = 45
Answer:
20 in.
Step-by-step explanation:
You can use similar triangle ratios to solve for this problem.
6/15=4/x, Now cross multiply to solve for x
6x=60, x=10 Find the perimeter
10+6+4=20, the perimeter of MNO is 20 in.
You did #1 correctly.
#2). The question gives you the equation, and the numbers to use for 'a' and 'b', and it just wants you to plug in those numbers and do the arithmetic.
It says: The number of tiles needed is (a²) divided by (b²).
Then it says: a = 96 and b = 8. I know you can handle that !
Number needed = (96)² divided by (8)² .
Use your calculator:
(96)² = 9,216
(8)² = 64
Number needed = (9,216) divided by (64) = 144 tiles
#3). While reading #3 carefully, I realized that there's a table printed near it,
and you need the table to do the problem. But you can't see the table in the
picture, so we're stuck on this one.
