I THINK THE ANSWER WOULD BE C
5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
Complete Question
We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed for a stack with a height of 50 cm
Answer:
37.5 cups
Step-by-step explanation:
Height 1 = 15cm
Number of cups = 6
Height 2 = 23 cm
Number of cups = 12
Hence:
H1 - H2/N1 - N2
= 15 - 23/6 - 12
= -8/-6
= 4/3
The number of cups that are needed for a stack with a height of 50 cm is calculated as:
50 cm ÷ 4/3
= 50 × 3/4
= 37.5 cups
Let us fill the blank squares in the 10-frame by the yellow circles below to make 10s.
1. Fill the 3 blank squares with 3 yellow circles below to make a 10 and form a new fact 10 + 2. Now, we can easily add 10 and 2 to get 12.
2. Fill the 1 blank square with 1 yellow circle below to make a 10 and form a new fact 10 + 4. Now, we can easily add 10 and 4 to get 14.
