First step is expand by using distributive property
<span>2(x + 7) + 3x = 12
step 1:
2x + 14 + 3x = 12</span>
Answer:
Measure of angle A = 55°.
Step-by-step explanation:
From the picture attached,


2 = 2
Corresponding sides of the given triangles ΔACB and ΔNLM are proportional.
Therefore, ΔACB ~ ΔNLM.
m∠A = 180° - (90° + 35°) [By triangle sum theorem]
= 180° - 125°
= 55°
Measure of angle A is 55°.
Answer:
That's the right answer.
Step-by-step explanation:
2x+3=3x
Subtract 2x from both sides
3=x or x=3
Answer:
B) 70.5
Step-by-step explanation:
Median = middle value when the values are placed in order.
If there are two middle values, the median is the mean of those two values.
<u>Class 1</u>
45 46 51 52 53 53 61 63 64 65 66 68 70 <u>70 71</u> 73 76 77 79 81 82 83 84 87 90 92 93 95
There are 28 values in Class 1.
Therefore, there are two middle values: 14th and 15th values
14th value = 70
15th value = 71
