Subtract
4x
from both sides of the equation.
y=−4+3x
y=−1−4x

On Monday, the low temperature in a city was -5.4°F. On Tuesday, the low temperature was 1.2°F colder than on Monday. On Wednesday, the low temperature was 3.7°F warmer than on Tuesday. What was the low temperature in the city on Wednesday?
Answer:
-2.9°F
Step-by-step explanation:
-5.4°F - 1.2°F = -6.6°F
-6.6°F + 3.7°F = -2.9°F
The low temperature in the city on Wednesday was -2.9°F
Hope this is helpful
Answer:
-2.9°F
Step-by-step explanation:
First subtract the temperature from Tuesday to Monday because it is getting colder, and you get 6.6 (-5.4 - 1.2 = -6.6)
Then add 3.7 because it is getting warmer and you get
-6.6 + 3.7 = -2.9

Simplify the following radical expression.
(7 + √13)(7 − √13)
Answer:
36
Step-by-step explanation:
(7+[tex]\sqrt{13[/tex] )(7-[tex]\sqrt{13[/tex] )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-([tex]\sqrt{13[/tex] )^2
=49-13
=36
[tex] \huge \mathrm{ \underline{Answer : }}[/tex]
The given expression can be written as :
[tex]( 7 + \sqrt{13} )(7 - \sqrt{13} )[/tex][tex](7) {}^{2} - ( \sqrt{13} ) {}^{2} [/tex][ by applying identity, (a+b) × (a-b) = a²-b² ]
[tex]49 - 13[/tex][tex]36[/tex]Therefore, we will get 36 as our simplified answer.

1/2(2x - 1) = -1/5 -3/5 find x
Answer:
x = -3/10
Step-by-step explanation:
1/2(2x - 1) = -1/5 -3/5
Combine like terms
1/2(2x - 1) = -4/5
Multiply each side by 2
2* 1/2(2x - 1) = -4/5*2
2x-1 = -8/5
Add 1 to each side
2x-1+1 = -8/5 +1
2x = -8/5+5/5
2x = -3/5
Divide by 2
2x/2 = -3/5 * 1/2
x = -3/10
Jesse has a storage container in the shape of a right rectangular prism. The volume of the container is 43.875 cubic meters, the length is 5 meters and the width is 3.9 meters.
What is the height of Jesse's storage container?
Answer:
The height is 2.25 meters.
Step-by-step explanation:
The volume of a right rectangular prism is the product of the length, width, and height. So it would be V=w*l*h.
Because you have been given the values of the volume, width, and length, you can plug in those values into the equation to find the height. It should look like this: 43.875=5 * 3.9 * h
Then you can divide both sides of the equation by 5 * 3.9.
So... 43.875/(5*3.9)=h
therefore h= 2.25.
hope this explanation makes sense!
The height of prism is 2.25 m.
What is Volume of Prism?Multiply the length, width, and height of a rectangular prism to determine its volume. Cubic measurements are used to express volume.
A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism. A rectangular prism also refers to a cuboid. A cuboid and a rectangular prism have the same cross-section.
given:
Volume of rectangular prism = 43.875 cubic meters
length = 5 m
Width = 3.9 m
Now, the volume of rectangular prism
V= l x w x h
43.875= 5 x 3.9 x h
h = 43.875/ (5 x 3.9)
h= 2.25 m
Hence, the height of prism is 2.25 m.

a bicyclist traveling at an average speed of 18 km/h takes 3 hours and 30 minutes to complete his journey. How many hours less will he take if he bicycles at a speed which is 3 km/h faster
Answer:
It will take him 0.5 (30 minutes) less hours if he bicycles at a speed that is 3km/h faster.
Step-by-step explanation:
18 km/h x 210 minutes = 3,780
3,780/21km = 180 minutes = 3 hours
If we multiply the speed by the time we can find the distance, using that we can find the time it takes to travel the same distance with more speed (21km/s this time).
Therefore, it will take 30 minutes less if he travels 2 km/s faster or 0.5 less hours
I hope this helps!

EXPLAIN WITH STPES (FIRST,THEN,NEXT,LAST)
ThanksQ
So you're trying to identify how many packs of ice cream cones Jim needs to buy if he needs 120 in total. To find this, first you have to find what number times 20 would get you 120. Then, you muitiply 6 by 20 to make sure it's 120. Once you do, you have your final answer.
Therefore, Jim needs to buy 6 packs to have a total of 120 ice cream cones.
I hope this information was of any use to you.
