Solve 1)3x-7=35? 2)22=7-3a 3)-d+7=3 4)2x+23=49 5)-c+2=5

astra-53 [7]

$1)\ 3x-7=35\ \ \ |add\ 7\ to\ both\ sides\\\\3x=42\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{x=14}\\-------------------------\\2)\ 22=7-3a\\\\7-3a=22\ \ \ \ |subtract\ 7\ from\ both\ sides\\\\-3a=15\ \ \ \ \ |divide\ both\ sides\ by\ (-3)\\\\\boxed{a=-5}\\--------------------------$

$3)\ -d+7=3\ \ \ \ \ |subtract\ 7\ from\ both\ sides\\\\-d=-4\\\\\boxed{d=4}\\---------------------------\\\\4)\ 2x+23=49\ \ \ \ \ \ |subtract\ 23\ from\ both\ sides\\\\2x=26\ \ \ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{x=13}\\---------------------------\\5)\ -c+2=5\ \ \ \ \ \ |subtract\ 2\ from\ both\ sides\\\\-c=3\\\\\boxed{c=-3}$

1. Choose the correct simplification of the expression −5x2(4x − 6x2 − 3).

nlexa [21]

1) 30x4 − 20x3 + 15x2

This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.

2) x3 + 8x2 + 13

Don't forget to check the terms sign. The subtraction symbol switches them all.

Solve the following word problem. A man travels from town X to town Y at an average rate of 60 mph and returns at an average spe

sladkih [1.3K]

Answer:

d = 1650 miles

Step-by-step explanation:

Let the distance be d

Then the time in travel is

d/60 one way, d/50 on return

The round trip would take 1/2 hours longer if the average speed was 55 mph

d/60 + d/50 = 2d/55 + 1/2
d/60 + d/50 - 2d/55 = 1/2

LCM(60,50,55) = 11*12*5*5 = 3300

55d/3300 + 66d/3300 - 120d/3300 = 1/2
d/3300= 1/2
d = 1650 miles

Answer question 10( I do not understand stand it)

omeli [17]

You would have to plot the vertices and play a sort of game of connect the plots ( *Or connect the dots but more literally, the plots*) Then decide whether or not your final illustrations have the potential to be similar. If so, why?

EXAMPLE ANSWER: DO NOT USE ANY IF THEM BELOW FOR I DO NOT KNOW THE UNIT LENGTH OR SHAPE THE CONNECTED DOTS WOULD CREATE!!!

The two triangles could be similar due to the identical amount of units between each vertice. Furthermore, you could connect the units in a certain orientation, keeping the units in mind, and produce two identical triangles.

Or...

The two triangles could be similar due to the type of triangle. Each triangle has the potential to be a (right/scalene/isosceles/obtuse/acute, etc).
