Answer:
65--but the method is the important part that the directions indicated.
Step-by-step explanation:
26 + 39
(2 × 13) + (3 × 13)
The GCF is 13.
Factor the 13 out; it's like Distributive Property in reverse.
13 (2 + 3)
13 (5)
65
26+39= 65, so we obtain the same answer as just adding, by using GCF and Distributive Property.
Answer:
13(2 +3)
Step-by-step explanation:
26 = 2·13
39 = 3·13
The greatest common factor is 13, so the sum can be written ...
26 +39 = 13(2 +3)
_____
Additional comment
Of course, the value of the sum is ...
13(2+3) = 13(5) = 65
Alternatively, the sum can be evaluated as ...
26 +39 = 26 -1 +1 +39 = (26 -1) +(1 +39) = 25 +40 = 65

Find the degree of the monomial. -20.5
Answer:
0
Step-by-step explanation:
-20.5 is the same as -20.5[tex]x^{0}[/tex], since anything to the zero power is equal to 1.
Answer:
The degree of a monomial is the sum of the exponents of the variables.
Therefore,
The degree of the monomial - 20.5 is 0, because there is no variables only numeric terms.
Step-by-step explanation:
To find the degree of monomial.
Basically,
- If one term is present, then it is monomial.
- If two term is present, then it is binomial.
- If three term is present, then it is trinomial.
- If more than three term is present, then it is polynomial.

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 8 large boxes and 4 small boxes has a total weight of 177 kilograms. A
delivery of 3 large boxes and 2 small boxes has a total weight of 73 kilograms. How much does each type of box weigh?
1. Weight of each large box ____ kilograms
2. Weight of each small box ____ kilograms
Answer:
Answer:
x = the wight of the large box
y = the weight of the small box
A delivery of 3 large boxes and 2 small boxes has a total weight of 73 kilograms.
3x + 2y = 73
A delivery of 8 large boxes and 4 small boxes has a total weight of 177 kilograms.
8x + 4y = 177
by solving the system of equations
3x + 2y = 73
8x + 4y = 177
we find
x = 15.5 kg
y = 13.25 kg
the large box weights 15.5 kg.
the small box weights 13.25 kg.
what is the equation of the line that passes through the point (0, -2) with a slope of 2
Answer:
Step-by-step explanation:
You can use a fill in the blank formula called "point-slope" formula because you were given a point and the slope. But there's an even easier way because they gave you a special point. The point (0, -2) is on the y-axis. So it actually IS the y-intercept. So just in this case, you can use the slope-intercept formula as a fill-in-the-blank formula bc you were actually given the slope (we always use m for slope) and the y-intercept.
This is y = mx + b... fill in the given slope for the m, fill in the y-intercept for the b, then you're done!

solve y:
7=4(3y-3)
Answer:
y=1.58
Step-by-step explanation:
7=4(3y-3)
Simplify the distributive property.
7=12y-12
Add 12 to both sides.
19=12y
Divide 12 on both sides.
1.58=y

8) The height of a stack of CD cases is Proportional to the number of CDs in the stack. A stack of 6 CDs is 66mm high.* Find the unit rate**
a) How high is a stack of 10 CDs?
b) Write an equation that relates the height (y) of a stack of CDs and the number of CD cases(x) in the stack.
please help I will mark your answer as brainliest
Answer:
a) 110 mm
b) y = 11x
Step-by-step explanation:
The unit rate for 6 CD at 66 mm is
66mm / 6 CD = 11 mm per CD
a) 10 CD's
66 mm x mm
--------- = ------------
6 CD 10 CD
Using cross products
66 * 10 = 6x
660 = 6x
Divide by 6
660/6 = x
110 mm for 10 CD's
b) y = 11 x
We use the rate and multiply by the number of cases to get the height
Can someone please take the time out of they’re day and help me and with this question
Answer:
see explanation
Step-by-step explanation:
(a)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 100) and (x₂, y₂ ) = (2, 200) ← 2 points on the line
m = [tex]\frac{200-100}{2-0}[/tex] = [tex]\frac{100}{2}[/tex] = 50
The line crosses the y- axis at (0, 100 ) ⇒ c = 100
y = 50x + 100 ← equation of line
where y is monthly savings and x the time in months
(b)
Slope is the monthly deposit , that is $50 per month
The y- intercept indicates the original amount in her account , that is $100

Answer:
48. 95,400 mL
50a. 331 yds.
50b. 11,916 in.
Step-by-step explanation:
Some helpful conversions can solve this for you :)
1 liter = 1000 mL
1 yard = 3 feet
1 feet = 12 inches
Now we get started!
48. We have 95.4 Liters, multiply by 1000 because 1000 mL per Liter. Therefore it's 95,400.
50
a. 3 feet per yard, so 993 feet divided by 3 is 331 yards.
b. 12 inches per foot, so 993 feet multiplied by 12 is 11,916

The area of a square is four times the area of a triangle. If the base of the triangle and a side of the square are equal, what is the ratio of the height of the triangle to the side of the square?
(A) 1 : 4
(B) 1 : 2
(C) 2 : 1
(D) 3 : 2
(E) 2 : 3
The ratio of the height of the triangle to the side of the square (B) 1 : 2
What are the areas of triangle and square?The area of a triangle is (1/2)×base×height.
The area of a square is (side)².
Given, The area of a square is four times the area of a triangle.
∴ (side)² = 4{(1/2)×base×height}.
The base of the triangle and the side of the square are equal let this be 'a'.
∴ a² = 4(1/2)×a×height.
a = 2×height.
a = 2h.

Answer:
#1= 5
#2= i think it's a red square
#3= 243
Step-by-step explanation:
ok so im rlly sorry but i think i can only solve 1 2 and 3:
for #1:
the pattern is subtracting 1,2,3,4 each time it goes to the next number.
29-28=1
28-26=2
26-23=3
23-19=4
19-?=5
?=14
19-14=5
so answer would be 5
for #2:
the pattern goes red triangle, red square, blue triange, blue square, red triangle, etc.
so with it continuing on, it would be red square
for #3:
the pattern looks like they're multiplying by 3 each time:
3x3=9
9x3=27
27x3=81
81x3=?
?=243
81x3=243
so the answer would be 243

How do I find the equation of the line?
Answer:
1.Identify the slope.
2.Identify the point.
4.Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) .
5.Write the equation in slope-intercept form.
Step-by-step explanation:
Answer:
y=-\frac{2}{3}x+3
Step-by-step explanation:
[tex]y=mx+b[/tex]
There are 4 variables in this equation, and 3 of them are already given. We already have the slope and the (x, y) of a known point. Plug those 3 into the equation and solve for b:
[tex]7=-\frac{2}{3}(-6)+b\\7=4+b\\b=3[/tex]
Now, with the slope and the y-intercept, you can write the equation of the line:
[tex]y=mx+b\\\\y=-\frac{2}{3}x+3[/tex]
