Answer:
the first one,the third one and the last.
You need two equations to solve a two-variable equation.
Answer: see below
<u>Step-by-step explanation:</u>
Speed = | Velocity |
4.
Velocity -14 20 -2 0 25 -15
Speed 14 20 2 0 25 15
5.
Velocity -16 16
Speed 16 16
6.
3 is greater then -4
|---------|---------|
-4 0 3
7.
A velocity of -4 has a greater speed than a velocity of 3
Velocity -4 3
Speed 4 3
Let Tritt's age = t & Jan's age = 2t - 3
if the sum of their ages equals 30 then..
combine terms and simplify
now simply divide
and to find Jan's age just plug 9 in
Jan's age = 15
Tritt's age = 9
Answer:
see below
Step-by-step explanation:
x+ 7.05 = 45.3
Subtract 7.05 from each side
x+ 7.05-7.05 = 45.3-7.05
x =38.25
Let x be the number
x+3.5 = -4.3
Subtract 3.5 from each side
x+3.5 - 3.5 = -4.3-3.5
x = -7.8
x is the cost of the drawing tablet
x+ 3.95 = 6.94 correct
The second equation add the total cost plus the cost of the drawing tablet and sets it equal to the cost of the pencils. This is not correct
6.94+x = 3.95 incorrect
