Answer:
1.75 inches or 1 3/4inches
Step-by-step explanation:
A map has a scale of ½½inch=20mles. Quinn wants to travel an actual distance of 70miles. What will the length on the map be?
70/20
=7/2
=1/2×7/2
=7/4
=1 3/4 inches
in decimal its 1.75 inches
14. 75 105
105 75
16. 155 25
155
17. 127
18. 55 125 125
19. 115 140 40
Answer:
D. y = |x| – 5.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
7+4y=7-5y+54
Collecting like terms
4y + 5y = 7 - 7 + 54
9y = 54
y = 54/9
y = 6
The equation -21t - 4 = 10 - 2t has only one solution
<u>Solution:</u>
Given, equation is – 21t – 4 = 10 – 2t
We have to find how many solutions does the above given equation have
Now, let us solve the given equation to find the number of solutions it has.
Then, - 21t – 4 = 10 – 2t
Taking like terms to one side of the equation we get,
- 21t + 2t = 10 + 4

here we can see only one value of t.
Hence, the given equation has only one solution.
