Answer:
x = 12
Step-by-step explanation:
The two marked angles are a linear pair, so are supplementary.
(8x -20)° +(8x +8)° = 180°
16x -12 = 180 . . . . . . . . . . . divide by °, collect terms
16x = 192 . . . . . . . . . . . add 12
x = 12 . . . . . . . . . . . divide by 16
Answer:
1070cm2
Step-by-step explanation:
the cereal box represents a cuboid and it is closed hence a closed cuboid.
SA- Surface area
L- Length = 15
W- Width =4
H- Height =25
In a closed cuboid, there are going to be 6 faces( 3 pairs).
To find SA, we have to take the area of all faces and sum them up.
You can do this by carrying out the area of all faces and summing them up or you can use the formula:
SA of a closed cuboid=2(L x W) + 2(W x H) + 2(L x H)
= 2(15 x 4) + 2(4 x 25) + 2(15 x 25)
= 2(60) + 2(100) + 2(375)
=120 + 200 + 750
=<u>1070cm2</u>
.5 (or 1/2) goes into 6 12 times. 12 x 20 = 240. Your answer is 240 miles.
-38 > -83
I have to use more charterers so I will explain it as well as I can. For example, If I am $38 in dept (-38) and you are $83 in dept (-83) who owes more money? Yes we both owe money but I owe LESS money.
Step-by-step explanation:
When w=10, 7w=7×10=70
But the given value of 7w is 73.
So, the given value is not a solution of the equation.
