which of the following is equivalent to 7x+5<-2(4x-3)
x>11
-x<1
15x<-11
15x<1
Answers
Answer:
7x+5< -8x+6
=15x<1
The equivalent inequality is 15x<1. Therefore, option D is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is 7x+5<-2(4x-3).
Now, 7x+5<-8x+6
Subtract 5 on both the sides of an inequality, we get
7x<-8x+1
Add 8x on both the sides of an inequality, we get
7x+8x<1
15x<1
Therefore, option D is the correct answer.

A pole that is 2.8 m tall casts a shadow that is 1.46 m long. At the same time, a nearby building casts a shadow that is 50.25 m long. How tall is the building?
Round your answer to the nearest meter.
Answers
Answer:
96 m
Step-by-step explanation:
Create a proportion where x is the height of the building:
[tex]\frac{2.8}{1.46}[/tex] = [tex]\frac{x}{50.25\\}[/tex]
Cross multiply and solve for x:
1.46x = 140.7
x = 96
So, the height of the building is approximately 96 m tall

7x-10y=3. Is this a
reasoning.
good model? Explain your reasoning.
Answers
Answer:
7x-10y=6
Step-by-step explanation:
Firstly, supervise 7x-10y=3 using the coordinates of one from the known points
7*8-10*5=3
6=3 It is not correct, so the equation is uncorect
Find the correct equation
The common equation is y=mx+b
5=8m+b
-9=-12m+b
Both equations are simultaneous.
-9-5= -12m+b- (8m+b)
-14=-20m
m=0.7
b=5-5.6=-0.6
y=0.7x-0.6
0.7x-y=0.6
7x-10y=6- the correct answer

11 Alicia buys a car that costs $26610, and she makes a $3140 down payment on it. How much
does she still owe on the car? Give units.
Answers
Answer:
$23,470
Step-by-step explanation:
A down payment is how much you pay upfront for a car. So, how much she still owes will be the difference between the total cost and the down payment. Therefore, subtract $3,140 from $26,610; 26610-3140=23470. Then, since you are talking about money the units are dollars, $.

what is the unit rate of 1/7 and 1/21 ? this is very confusing?
Answers

the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.
Step-by-step explanation:
this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.

15) A small rectangular block of land has a perimeter of 100 m and an area of 225 m². Find the dimensions of the block of land.
Answers
Answer:
45 and 5 are the dimensions of the block of land.
Step-by-step explanation:
2(x + y) = 100, x + y = 100/2, y = (50 - x)
xy = 225
x (50 — x) = 225
0 = x^2 — 50x + 225
0 = (x — 45) (x -5)
45 and 5 are the roots of the above polynomial, thus they are the sides or dimensions of the block of land.
