Answer:
Step-by-step explanation:
<u>We know that:</u>
- Rule: Always simplify the innermost bracket first.
- Given expression: 35 - {15 - (19 + 5)} ÷ 3
<u>Solution:</u>
- 35 - {15 - (19 + 5)} ÷ 3
- => 35 - {15 - (24)} ÷ 3
- => 35 - {15 - 24} ÷ 3
- => 35 - {-9} ÷ 3
- => 35 + 9 ÷ 3
- => 35 + 3
- => 38
Hence, the simplified answer is 38.
Answer:
90
Step-by-step explanation:
Find total marks needed for a 90.
90 x 4 = 360 marks
Then, add up the marks on the three tests.
83+91+86 = 260 marks
Finally, subtract from the 360 marks needed.
360 - 260 = 100
Thus, the student needs to score 100 marks in order to get a 90.
Answer:
1 cup of blue paint required 5 cups of yellow paints
<em />
Step-by-step explanation:
Given
2 cups of blue = 10 cups of yellow
Required
Determine the number of cups of yellow for 1 cup of blue paint
The given parameter shows a linear relationship between paints of blue and paints of yellow
We have:
2 cups of blue = 10 cups of yellow
Multiply both sides by 0.5
0.5* 2 cups of blue = 0.5* 10 cups of yellow
1 cup of blue = 5 cups of yellow
Hence;
<em>1 cup of blue paint required 5 cups of yellow paints</em>
