Options :
A. 7x -(7x+20)=700
B.7x + 7(x+20) =700
C. 7x + (7x-20)=700
D.7x - 7(x-20) =700
Answer:
B.) 7x + 7(x+20) =700
Step-by-step explanation:
Given that :
Dave and Steven are 700m apart
They start walking towards each other and meet after 7 minutes
Distance covered by Dave per minute = x
Distance covered by Steven per minute = x + 20
rate = distance per minute
Dave's rate = x / minute
Steven's rate = (x + 20) / minute
Distance = rate * time
Distance covered by DAVE :
X /min * 7 = 7x
Distance covered by STEVEN :
(x + 20) * 7
= 7(x + 20)
Hence, the sum of distances covered by both Dave and Steven should add up to the total distance :
7x + 7(x + 20) = 700

how to comoplete Samantha is 4 feet, 3 inches tall. What is her height in inches?
Answer:
51
Step-by-step explanation:
4*12=48
48+3=51
one foot = 12 inches
Samantha's height in inches is 51 inches.
To find Samantha's height in inches, we need to convert her height from feet and inches to inches. We know that 1 foot is equal to 12 inches. Therefore, we can convert her height in feet and inches to inches using the following steps:
Step 1: Convert her height in feet to inches. Samantha is 4 feet tall, so her height in inches due to feet is 4 * 12 = 48 inches.
Step 2: Add the additional height in inches. Samantha is also 3 inches tall, so we add 3 inches to the previous result.
48 inches (from feet) + 3 inches = 51 inches
Samantha's height is 51 inches.
In conclusion, Samantha's height in inches is 51 inches.

Rectangle RSFT has vertices R(3,10), S(5,10), F(5,6) and T(3,6). RSFT was reflected over the line
y = x, to form R'S'F'T'. What are the coordinates of the vertices of the image?
Answer:
The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)
Step-by-step explanation:
If the point (x, y) reflected across the line y = x, then its image is (y, x)If the point (x, y) reflected across the line y = -x, then its image is (-y, -x)Let us use the first rule above to solve the question.
∵ Rectangle RSFT has vertices R (3, 10), S (5, 10), F (5, 6), and T(3, 6)
∵ RSFT was reflected over the line, y = x
→ To find its image switch the coordinates of all the vertices
∵ R = (3, 10)
∴ R' = (10, 3)
∵ S = (5, 10)
∴ S' = (10, 5)
∵ F = (5, 6)
∴ F' = (6, 5)
∵ T = (3, 6)
∴ T' = (6, 3)
The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)

Answer:
y-1=4(x+2)
Step-by-step explanation:
plug the point in
An equation in the point-slope form of the line that passes through the given point and with the given slope m is y-1=4(x+2).
We have given that,
slope m=4 and the point (-2,1)
What is the slope point form of the line?
The slope point form of the line is
[tex](y-y_1)=m(x-x_1)[/tex]
use the given values in the above slope point form so we get,

Mathematic Help Please
Answer:
Angle 1 is 62
Angle 2 is 45
Angle 3 is 24
Step-by-step explanation: from
To get angle 1 you subtract 118 from 180 (180-118) and get 62
For angle 2 you subtract 62 and 73 from 180 (180-62-73) and get 45
For angle 3 you first subtract 73 from 180 (180-73) and get 107 then subtract 107 and 49 from 180 (180-107-49) and get 24
You subtract everything from 180 because with straight lines they are equal to 180 degrees and triangles are also equal to 180 degrees
Answer: m 1= 62 m 2= 45 m 3=58
Step-by-step explanation:The angles of a triangle equal 180. You subtract the angles that you know from 180 and the answer you're left with is the answer. The last one has an extra step because it only gives you one angle so to find the angle right next to 73 you subtract 73 from 180 which is 107 and then you subtract 49 from that which is 58.

A football team needs to move the ball at least 10 yards forward from the original starting point in order to get a first down. Angel runs for 6 yards on the first play. On the second play, he is sacked for −9 yards. At least how many yards does his team need on the third play to get a first down?
Answer:
13 yards
Step-by-step explanation:
Given that:
To get a first down, ball needs to be moved 10 yards forward from original starting point.
Distance on first play = 6 yards
on second play = - 9 yards
Hence to get a first down, distance on third play should be:
Let distance needed on third play = d
Hence,
Sum of distance on all three plays should be = 10
6 + (-9) + d = 10
6 - 9 + d = 10
-3 + d = 10
d = 10 + 3
d = 13 yards
