Answer: X= -15
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The answer is D (5/4). We go up by 5 and to the side we go 4 in order to get between the points (0,8) and (-4,3). We know it’s rise over run. The rise is 5 because we go up by 5 and the run is 4 because we go to the side 4 times. By looking from left to right at the line, we see it’s a going to be positive. This means the answer is 5/4.
Answer:
you have the answer correct actually
Step-by-step explanation:
Answer:
175 ft
Step-by-step explanation:
From the question,
(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal
100/d = 4x/7x
100/d = 4/7
where d = distance across the river
solve for d
d = (100×7)/4
d = 175 ft
