They are all vertical angles.
Answer:
69.993
Step-by-step explanation:
Using the percentage error formula:
Percentage error = (true - measured value / true measurement ) * 100%
1% error in measurement
1% of 69.3
0.01 * 69.3 = 0.693
True measurement = error in measurement + measured value
True measurement = 0.693 + 69.3
Actual measurement = 69.993
Hence, actual measurement = 69.993.

1. Distribute 6 to both 2x and -3
5+12x-18-4x
2. Combine like terms
8x-13
Answer:
7 Zuchini, 14 Cucumbers and 22 Tomatoes plants.
Step-by-step explanation:
- Let the number of tomatoes=t
- Let the number of cucumber planted=c
- Let the number of zucchini planted=z
- Total Number of Plants=43
She planted twice as many cucumbers as zucchini, this is written as:
She also planted eight more tomatoes than cucumbers, this is written as:
In total, she planted 43 plants
Therefore:
z+(2z)+(2z+8)=43
5z+8=43
5z=43-8
5z=35
Divide both sides by 5
z=7
Number of Cucumbers, c=2z=2 X 7 =14
Number of Tomatoes, t=c+8=14+8=22
Therefore, she planted 7 Zuchini, 14 Cucumbers and 22 Tomatoes plants.
Step-by-step explanation:
We observe the line graph.
For every 1 block across, the line goes up by 2 blocks. Therefore Slope = Rise/Run = (2)/(1) = 2.
Also, the y-intercept when x = 0 is 2.
Slope-intercept form: y = mx + c
Hence we have y = 2x + 2. (C)
