21 hours in May, 63 hours in JuneStep-by-step explanation:
Set up equationsm - May, j - Junem + j = 84m = 1/3jSolve by substitution, fin the value of j1/3j + j = 844/3j = 84j = 84*3/4j = 63Find mm + 63 = 84m = 84 - 63m = 21May be y and June be x
x+y=84y=1/3xNow
Put y from (2) in eq(1)
x+1/3x=843x+x)3=844x/3=844x=3(84)x=3(21)x=63Find y

At the beginning of Jack's diet, he was 257 pounds. If he lost 3 pounds per week, find his weight after
12 weeks.
Answer:
A loss of weight means we subtract from Jack's current weight.
Step-by-step explanation:
A loss of weight means we subtract from Jack's current weight. New Weight = Current Weight - Weight Loss per week * number of weeksNew Weight =257 - 3*12New Weight =257 - 36New Weight = 221
I need help on this question
Step-by-step explanation:
the area of a rectangle is
length × width.
our job here is to find all integer values for length and width, so that their product is 90.
that means that length and width are both factors of 90.
the factors of 90 are
1 × 90
2 × 45
3 × 30
5 × 18
6 × 15
9 × 10
10 × 9
15 × 6
18 × 5
30 × 3
45 × 2
90 × 1
the prime number grouping
is
2 45 (can't be divided by 2 anymore, so,
next prime factor)
3 15
3 5 (can't be divided by 3 anymore, so
next prime factor)
5 1 (the end)
so, besides 1 and these prime factors, the only other factors are combinations of these prime factors :
2×3 = 6
2×5 = 10
3×3 = 9
3×5 = 15
2×3×3 = 18
2×5×3 = 30
3×5×3 = 45

Find the y-intercept of the line 19x - 13y = 26.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.
Answer:
y - intercept = - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
19x - 13y = 26 ( subtract 19x from both sides )
- 13y = - 19x + 26 ( divide terms by - 13 )
y = [tex]\frac{19}{13}[/tex] x - 2 ← in slope- intercept form
with y- intercept c = - 2
The y-intercept of the line equation 19x - 13y = 26 is 2.
Given that, the y-intercept of the line 19x - 13y = 26.
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
The given equation can be written in standard form as
13y=19x-26
⇒ y=19/13 x-26/13
⇒ y=19/13 x-2
So, y-intercept =2
Therefore, the y-intercept of the line equation 19x - 13y = 26 is 2.

The sum of two numbers is -18. If the first number is 10, which equation represents this sittuation, and what is the second number
Answer:
-28
Step-by-step explanation:
Since the first number is 10 and they say and the equation said two numbers sum - 18 therefore 10 + x equals to -18
=> 10 + x = -18
now to find the second number collect like terms make x the subject of formula
=> x = -18 -10
substract -18 from -10
x = -28
-28 is your final answer

Maya started to run on a treadmill after setting its timer for 99 minutes. The display says that she has finished 27% of her run. How many minutes have gone by? Round your answer to the nearest tenth. minutes
Answer:
26.73 minutes have gone by
Step-by-step explanation:
Use cross multiplicationx 27
---- = ----- since we are trying to find how many minutes out of 99 passed,
99 100 place x for the missing digit
solvex times 100 = 99 times 27
simplifyx100 = 2673 x times 100 is just x100 since we don't know what x is, and 99
times 27 is 2673
figure for xx100 = 2673 to find x, it needs to be alone (x is very introverted :'> ) we can
---- ------- remove 100 by doing the opposite of what 100 is doing to the
100 100 x. Since it is 100 TIMES x, we will remove it by dividing 100 by
100 (which crosses it out) and then 2673 divided by 100. 2673
x = 26.73 divided by 100 gives us 26.73, so x equals 26.73.

You are wrapping a birthday gift that is packaged in a specially made pyramid-shaped box. The base of the box measures 10 inches by 10 inches and the slant height is 6 inches. How much paper do you need to wrap the box?
Answer:
2 1/4
Step-by-step explanation:
The amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches
What is the surface area of cuboid?Let the three dimensions(height, length, width) be x, y,z units respectively.
The surface area of the cuboid is given by
[tex]S = 2(a\times b + b\times c + c\times a)[/tex]
A box is usually in shape of a cuboid.
For this case, its dimensions are 10 inches, 10 inches, and 6 inches.
The amount of wrapper we need is approx same as the area of its surface (assuming we're going to measure the paper needed in terms of its area).
Thus, we get:
Amount of the paper we need to wrap the considered box = surface area of that box = surface area of cuboid of dimension 10 inch by 10 inch by 6 inches = S (say), then:
[tex]S = 2(10\times 10+ 10\times 6 + 6\times 10)\\S = 440[/tex](in sq. inches)
Thus, the amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches
