Answer:
p = -3
Step-by-step explanation:
-2 (p - 5) + 7p = -5
-2p + 10 + 7p = -5
5p = -15
p = -3
Answer:
y = 3x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = 12 + c ⇒ c = 3 - 12 = - 9
y = 3x - 9 ← equation of line
Total length of wire = 9.8 m
It will be cut into 0.14m of pieces.
Number of wires
= (9.8/0.14) wires
= 70 wires
Answer:
C; It shows the cost of the other situation, and if you do cross/multiply/divide, you will get the overall cost of 13 glue sticks using the proportion.
Step-by-step explanation:
output is 3 times of input so it's like this x ➡ 3x
