2.
18/x = 6/10
6* x = 18 * 10
6x = 180
x = 30

3.
t/6 = 30/36
36t = 6 * 30
36t = 180
t = 5

5.
2.5/35 = 2/d
2.5d = 35 * 2
2.5d = 70
d = 28

6.
3.5/18 = z/36
3.5 * 36 = 18z
126 = 18z
7 = z

8.
2.4/6 = 2.8/s
2.4s = 6 * 2.8
2.4s = 16.8
s = 0.7

9.
3.6/k = 0.2/0.5
3.6 * 0.5 = 0.2k
1.8 = 0.2k
9 = k

hope this helped!! :)

Claire traveled 701 miles. She drove 80 miles every day. On the last day of her trip she only drove 61 miles. Write and solve an
mina [271]

Answer:

Claire traveled for 9 days.

Step-by-step explanation:

Given:

Total Distance traveled = 701 miles

Distance traveled each day = 80 miles

Distance traveled on last day = 61 miles

We need to find the number of days Claire traveled.

Solution:

Let the number of days Claire traveled be denoted by 'd'.

Now we can say that;

Total Distance traveled is equal to sum of Distance traveled each day multiplied by number of days and Distance traveled on last day.

framing in equation form we get;

80d+61=701

Now Subtracting both side by 61 using Subtraction Property of Equality we get;

80d+61-61=701-61\\\\80d = 640

Now Dividing both side by 80 we get;

\frac{80d}{80}=\frac{640}{80}\\\\d=8

Hence Claire traveled 80 miles in 8 days and 61 miles on last day making of total <u>9 days</u> of travel.

Using the rules for special cases, what is the result of?
Arlecino [84]

Answer:

C) 4x^2 -8x +4[/tex]

Step-by-step explanation:

(-2x+2)^2

we apply (a+b)^2 formula

(a+b)^2 = a^2 + 2ab +b^2

a= -2x  and b= 2

Replace 'a' with -2x  and 'b' with 2

(-2x+2)^2 = (-2x)^2 + 2(-2x)(2) +2^2

(-2x)^2 is 4x^2

(-2x+2)^2 = 4x^2 -8x +4

option C is the answer

Evaluate the step function for the given input values. g(x) = g(2) = g(–2) = g(5) =
romanna [79]

Answer:

Step-by-step explanation:

g(2) = g(–2) = g(5) is never true for the step function.  One " = " symbol per pair of g values, please.

The step function, which you're calling "g(x)," is 0 from -infinity up to but not including 0.  It's 1 from x just greater than 0 through infinity.

Thus:

g(2) = 1 because x is greater than 0.

g(-2) = 0 because x is less than 0.

g(5) = 1 because x is greater than 0.

ANSWER FOR BRAINLIEST AND EXPLAIN!! :)
KengaRu [80]

Answer:

x = 6

Step-by-step explanation:

All triangle angles add up to 180 so:

90 + 5x + 6 + 54 = 180

5x + 150 = 180

5x = 30

x = 6
