It is £15 for the words, but I don’t understand the second part
Answer:
18
Step-by-step explanation:
Product of 7 and a number is 126.
Let's form the equation,
→ 7 × x = 126
The required value of x will be,
→ 7 × x = 126
→ x = 126/7
→ [ x = 18 ]
Hence, the number is 18.
Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
Move the 11x to the left and the +54 to the right. Their signs will flip:
14x-11x = 96-54
3x = 42
x = 14
