Answer:
Quiana has 8 text messages from Pierre.
Step-by-step explanation:
This question can be solved using a rule of three.
Quiana has 7 times more text messages from Yolanda than from Pierre.
This means that for each message that she receives from Pierre, she receives 7 from Yolanda.
She received 56 from Yolanda.
So
7 messages from Yolanda - 1 messages from Pierre
56 messages from Yolanda - x messages from Pierre
Quiana has 8 text messages from Pierre.
Answer:
Step-by-step explanation:
x + 5(-x - 2)= 2
x - 5x - 10 = 2
-6x - 10 = 2
-6x = 12
x = -2
y = 2 - 2 = 0
(-2, 0)
answer is no
Answer:
Step-by-step explanation:
<em>See attachment for number line</em>
From the attachment, we have the following details:
The first shade of blue covered 10 blocks
The second shade of blue covered 5 further blocks which totaled to 15
So, the fraction of the blue blocks is:
Divide fraction by 5/5
Also from the attachment:
The shaded block stopped at the fraction:
So, the expression that represents this scenario is:
<em>Option (c) answers the question</em>
Answer:
Step-by-step explanation:
if they are Pythagorean triples they should check for the theorem
the biggest value 17/8 should be the hypothenuse
(17/8)² = 1² + (15/8)² ; square the numbers
289/ 64 = 1+ 225/ 64 ; find the common denominator for addition
289/ 64 = 64+ 225/ 64 ; add
289/ 64 = 289 /64 TRUE so they are Pythagorean Triples
Answer:
1 to 30 seconds
Step-by-step explanation:
3 seconds increases your speed from 32 to 35 miles per hour
Hence 3 seconds = 3 miles per hour(35-32 miles)
1 second = 1 mile
The function for the increase per mile is therefore:
f(x)= 1x
Where x is number of seconds travelled on the highway
The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)
