Answer:
x = -0.2
Step-by-step explanation:
Cross multiply
9* 0.2(6x + 1) = 3.6 * 0.5x Combine the coefficients on the right.
1.8 (6x + 1) = 1.8 x Remove the brackets on the left
1.8*6x + 1.8 = 1.8x Multiply the factors on the left. Don't do anything with the plus sign
10.8x + 1.8= 1.8x Subtract 1.8 from both sides
10.8x = 1.8x - 1.8 Subtract 1.8x from both sides
10.8x - 1.8x = -1.8
9x = - 1.8 Divide by 9
x = -1.8/9
x = - 0.2
Check
This is one question you should check. There's lot's of room for an error.
<em><u>LHS</u></em>
0.2(6x+1)/3.6
0.2(6 * -0.2 + 1) / 3.6
0.2( - 1.2 + 1) / 3.6
0.2( - 0.2) / 3.6
- 0.04 / 3.6
- 0.011111111
<em><u>RHS</u></em>
0.5 ( - 0.2)/9
-0.1/ 9
- 0.0111111 And the left and right side check.
Option B. Quotient is the right answer
Step-by-step explanation:
Given expression is:
p/2 +4(7+p)
Let us look at the options one by one
<u>A. factor</u>
p/2 is not a factor as the factor is always multiplied with another factor
<u>B. quotient</u>
This is the right answer as p is being divided by 2. The quotient of both will be used for further calculations
Hence,
Option B. Quotient is the right answer

Answer:
See below.
Step-by-step explanation:
Here is an example:-
Solve by elimination:
2x - 3y = 0
3x + 2y = 13
To eliminate the y terms Multiply the first equation by 2 and the second by 3. This gives:
4x - 6y = 0
9x + 6y = 39 Adding the 2 equations:
13x + 0 = 39
13x = 39
x = 39/13 = 3
Finally we find y by plugging x = 3 into the first equation:
2(3) - 3y = 0
3y = 2(3) = 6
y = 2.
So basically 3cm is the model and 2 m is the actual size. So the hood is 1m so it is half of 2m which means the answer to the question is 1.5cm
Answer:
Step-by-step explanation:
The answer is 7 first take away the last number don’t throw it away you still need it but just to make it easier then you do 8-3 which is 5 so then bring the last number back and you add 2 which gives you 7 as your answer
