The answer is B. If 1 kilogram is 1,000 grams and mary needs 2 kilograms of potatoes she would multiply 2 by 1,000 equaling 2,000.
The numbers are 24 and 26
Step-by-step explanation:
- Step 1: Let the integers be x and (x+2). Here the smaller integer is x and the larger integer is x + 2.
Given that 4x = 18 + 3(x + 2)
⇒ 4x = 18 + 3x + 6
⇒ 4x = 24 + 3x
⇒ x = 24 and x + 2 = 26
If you know the total length, and the length of one part, and you're trying to find the other part, just subtract.
81-53=28
bc=28
Step-by-step explanation:
Let x be the number of Green apples bought.
Then 4x is the number of Red apples bought.
We have x + 4x = 50, so x = 10.
Since there are 10 green and 40 red apples, 40 - 10 = 30 more red apples than green apples.
Answer:
C.
Step-by-step explanation:
x is bisecting the baseline (cutting it in 2 halves of 6).
the third angle in the main overall triangle is 60 degrees.
remember, all angles in a triangle always add up to 180 degrees.
so, 180 - 60 - 60 = 60.
that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.
=> y = 12
and now using Pythagoras to calculate the height (x) of the triangle :
y² = x² + 6² (remember, this side is only half the baseline)
12² = x² + 6²
144 = x² + 36
x² = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)
