Answer:
x = 1/9.
Explanation:
-4(2x - 5) – (7 – 3x) = 4(x + 3)
-8x + 20 - 7 + 3x = 4x + 12
-8x + 3x - 4x = 12 + 7 - 20
-9x = -1
x = 1/9.
The answer is to isolte the unknown on one side by itself so
I hope you know how number lines because It is hard to do on branly so
1.
h-16 <u><</u>-24
add 16 to both sides
h<u><</u>8
graph
2. y+6 <u>></u>-13
subtract 6
y<u>></u>-19
graph
3. -3<n-8
add 8 to both sides
5<n
graph
4. 3<u><</u>m+1.4
subtract 1.4 from both sides
1.6<u><</u>m
graph
5. x+0.7>-0.3
subtract 0.7 from both sides
x>-1

6. w-8<u>></u>5.6
add 8 to both sides
w<u>></u>13.6

Answer:
14. 58 degrees
16. 11 degrees
Step-by-step explanation:
14. The sum of all 3 interior angles of a triangle is 180. We know right angles are 90 degrees. So 180 - 90 - 32 = 58 degrees
16. When two parallel lines are cut by a transversal, the corresponding angles have the same measure. So the angle above angle a has the same measure as the 169 degree angle in the same position on the other line. I hope those words make sense. Then angle a and the angle above it (which we know = 169 degrees) combine to make a straight line/straight angle, which = 180 degrees. 180- 169 = 11
Please let me know if you have questions.
We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.
To find the time it took, divide the distance by his speed:
325 miles / 65mph = 5 hours.
