Solve z = -10x, for x.

Answers

Answer:

Step-by-step explanation:

z = -10x

z + 10 = -10x + 10 = x

Answer: D

If z = -10x, we can divide both sides of the equation by -10 to get z/(-10) = x. This is the same as [tex]x=-\frac{z}{10}[/tex].

The online price for a box of hair clips is $2.60. For any number of boxes purchased, the cost of shipping is $12. The equation c=2.60b + 12 represents the total cost, c, of ordering b boxes of hair clips. If Mrs. Hilton orders 32 boxes of hair clips, what is the total cost? (6.EE.C.9)

Answers

Answer:

$43.2

Step-by-step explanation:

Step one:

given data

the total cost function is

c=2.60b + 12

Step two:

Required is c, when b= 12

substitute b=12 we have

c=2.60(12) + 12

c=31.2+ 12

c=43.2

the total cost = $43.2

Mary can read 22 pages in 30 minutes. How long would it take her to read a 100 page book? Write your answer in hours and minutes

Answers

Answer:

Step-by-step explanation:

Step one:

given data

we are told that Mary can read 22 pages in 30 minutes (0.5 hours)

let us find the number of pages per minute she can read

rate= quantity/time

rate= 22/30

rate=0.73 pages per minute

rate= 22/0.5

rate= 44 pages per hour

Step two:

Required

time taken to read 100 pages

t= quantity/rate

t=100/0.73

t=136 pages per minute

t= 100/44

t=2.3 pages per hour

How do I do this? Anyone know

Answers

Answer:

62 degrees

Step-by-step explanation:

Every triangle adds up to 180 degrees.

Since you already know two angles, you subtract them from 180 to find the final angle.

180-68.5-49.5=62

Answer:

x=62

Step-by-step explanation:

the sum of the angles of a triangle is always 180 degrees.

so x + 68,5 + 40,5 = 180°

=> x = 180 - (68,5 + 40,5)

=> x = 62

What is a right triangle?

A triangle with one of its angles measuring 90° is known as a right triangle.

Given a right triangle with a hypotenuse of length 58 and a leg of length 32.

Use the sine rule:

(sin90°) / 58 = (sinx) / 32

sinx = 32/58

x = sin⁻¹ ( 32/58)

x = 33.49°

Hence, the value of x is 33.49°.

Which is an equivalent equation solved for the slope, m? m = yx + b m = m equals StartFraction y minus b Over x EndFraction. m = m equals StartFraction y Over x EndFraction minus b. – b m = y – m equals y minus StartFraction b Over x EndFraction.

Answers

Answer:

m equals StartFraction y minus b Over x EndFraction

Step-by-step explanation:

The standard equation of a line is expressed as;

y = MX+b where;

m is the slope

cmb is the intercept

We are to get the equivalent expression for finding the slope.

Make m the subject of the formula to get this as shown;

From the equation;

y =MX+b

Subtract c from both sides;

y-b = MX+b-b

MX = y-b

Divide through by x;

mx/x = (y-b)/x

m = (y-b)/x

Heme the required expression is m = (y-b)/x OR m equals StartFraction y minus b Over x EndFraction

Jamal hiked on two trails. The first trail was 8 1 3 miles long, and the second trail was 1 3 5 times as long as the first trail. How many miles did Jamal hike? Enter your answer as a mixed number in simplest form.

Answers

Answer:Total distance( miles ) covered by Jamal =21 2/3 miles

Step-by-step explanation:

Step 1

first trail = 8 1/3 miles long

2nd trail = 1 3/5 times as long as the first

Therefore the distance walked in the 2nd trail is 1 3/5 x 8 1/3

changing to improper fraction and solving

=8/5 x 25/3= 40/3

The distance hiked by Jamal in the second trail = 40/3=13 1/3

Step 2

Total distance( miles ) covered by Jamal = first trail +2nd trail

= 8 1/3 + 13 1/3 =21 2/3 miles

Answer:

21 2/3 miles

Step-by-step explanation:

First trail = 8 1/3 miles long

Second trail = 1 3/5 times as long as the first trail

= 1 3/5 × 8 1/3

= 8/5 × 25/3

= 40 / 3

= 13 1/3 miles

How many miles did Jamal hike?

Total miles hiked = First trail + Second trail

= 8 1/3 miles + 13 1/3 miles

= 25/3 + 40/3

= 25+40/3

= 65/3

= 21 2/3 miles

Jamal hiked 21 2/3 miles

Why was it important for the colonies to win the support of the French Utah College adopted a policy designed to produce a more diverse student body. Under the policy, the college uses a selection index on which an applicant may score a maximum of 150 points. Those whose point totals are 100 or above are certain to be admitted; those with fewer than 75 points are likely to be rejected; and those with between 75 and 99 points may or may not be accepted, the likelihood of admission increasing with their scores. Of the 150 possible points, up to 110 may be awarded for academic performance factors, including high school grade point average, standardized test scores, and quality of the high school. Up to 40 additional points may be assigned for other, non-academic factors, such as in-state residency, alumni relationships, personal essay, and personal achievement or leadership. Most of these nonacademic factors carry a low number of points (e.g. 3 for an outstanding essay, 5 for personal achievement or leadership, and 10 for in-state residency). However, any applicant who is an underrepresented minority receives 20 additional points. Is the Utah College student diversity policy constitutional under the Equal Protection Clause of the 14th Amendment? a)No, because race cannot be considered at all in college admissions. b) Yes, because the policy does not reserve any seats for underrepresented minorities.c) Yes, because obtaining a more diverse student body qualifies as compelling interest.d) No, because race is weighed very heavily as a plus factor that is dispositive in most cases.
