Answer:
36 more students of grade 7 went on a trip than students of grade 6
Step-by-step explanation:
60 % of 110 students= 60/100*110= 66 students
85 % of 120 students= 85/100 * 120= 102 students
No of students of grade 7th more than 6th grade students= 102-66= 36
Answer:
Slope = - 1/3
Step-by-step explanation:
Y2-Y1 / X2 - X1
Answer:
x = -10/13
Step-by-step explanation:
10x + 7 = -3x - 3
Add 3x to both sides
10x + 3x + 7 = -3x + 3x - 3
13x + 7 = 0x - 3
13x + 7 = -3
Subtract 7 from both sides
13x + 7 - 7 = -3 - 7
13x + 0 = -10
13x = -10
Divide both sides by 13
13x ÷ 13 = -10 ÷ 13
1x = -10/13
x = -10/13
Answer:
Equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Step-by-step explanation:
The distributive property says that:
![a \cdot (b+c) = a\cdot b + a\cdot c](https://tex.z-dn.net/?f=a%20%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%20%2B%20a%5Ccdot%20c)
Given the expression: ![9(2a+1)](https://tex.z-dn.net/?f=9%282a%2B1%29)
Apply the distributive property:
![9 \cdot (2a) +9 \cdot 1](https://tex.z-dn.net/?f=9%20%5Ccdot%20%282a%29%20%2B9%20%5Ccdot%201)
Simplify:
![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Therefore, the equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
