Answer:
21/8
Step-by-step explanation:
3/8 x 7/1 = 21/8
Answer:
(21/8) (no parenthesis required)
or
2 and 5/8 (no "and" required)
Step-by-step explanation:
When you divide fractions, multiply the first number by the reciprocal of the second (2/3's reciprocal is 3/2 and 5/8's reciprocal is 8/5)
3/8 ÷1/7
= (3/8)*(7/1)
then multiply the numerators together and put them over the denominator
=21/8
= 2 and 5/8
Find the y-intercept of the line y=-4x +2. Write the point as a coordinate (x,
y). *
Answer:
(0, 2)
Step-by-step explanation:
You know the x-value has to be 0 in a y-intercept then you get you y-value by looking at b (assuming you are using y = mx + b) to get your y-value
I just wanna know how I solve this: "Select the division equation that can be used to find the solution to the problem. 4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost? "
9514 1404 393
Answer:
$4.50
Step-by-step explanation:
To find cost per kilogram, divide the cost by the number of kilograms it corresponds to.
($2)/(4/9 kg) = (2)(9/4) $/kg = $4.50 /kg
1 kilogram costs $4.50.

(28 ⋅ 3−5 ⋅ 60)−2 ⋅ 3 to the power of negative 2 over 2 to the power of 3, whole to the power of 4 ⋅ 228
The answer would look like this:
(2^8 × 5^–5 × 19^0)–2 ×× 228 = (2^–16 × 5^10 × 19^0) × × 2^28 = (2^–16 × 5^10 × 1) × × 2^28 = (2^–16 × 5^10 × 1) × 5^–8 × 2^–12 × 2^28 = (2^–16 × 2^–12 × 2^28) ×(5^10 ×5^–8) = 2^–28 × 2^28× 5^2 = 2^0 × 25 = 25

help me A box of cereal weighs 600 grams. How much is this weight in pounds? Explain or show your reasoning. (Note: 1 kilogram = 2.2 pounds)
The box of cereal weighs
Question Blank
type your answer...
pounds.
Answer:
1.32lb
Step-by-step explanation:
We will first have to calculate the grams to kilogram,
600g = 0.6kg
Since 1 kilogram represents 2.2 pound we will multiply 0.6 by 2.2 to get the pounds
0.6 * 2.2
= 1.32lb

110 meters of fencing are used to fence a rectangular pasture of 750 square meters of farmland. If the length of the pasture is longer than the width, what is the width of the pasture in meters?
Answer:
25mStep-by-step explanation:
Perimeter of the rectangular pasture P = 2(L+W)
Area A = LW
L is the length
W is the width
Given
Perimeter = 110m
Area = 750m
If the length of the pasture is 40m longer than the width, then L = W+40
110 = 2L+2w
55 = L+W .....1
750 = LW.....2
Solving simultaneously
from 1; L = 55-W
substitute into 2;
750 = (55-W)W
750 = 55W-W²
-W²+55W -750 = 0
W²-55W+750 = 0
(W²-25W)-(30W+750) = 0
W(W-25)-30(W-25) = 0
(W-25)(W-30) = 0
W-25 = 0 and W-30 = 0
w = 25m and 30m
Since L = 55-W
L = 55-25 = 30m and;
L = 55-30 = 25m
Since we are told that length id longer than the width then, the width we are going to use is 25m
Violet is trying to start an Intramural Club at her school. The principal tells her she must get signatures from students to show support. Each filled sheet contains 25 signatures. By Monday, she and her friend already have 6 sheets filled with signatures. The principal tells Violet she must have 7 more sheets filled with signatures. Write an equation for the number of signatures Violet will get. If she fills all of these, how many signatures will she get in all?
Answer:
325
Step-by-step explanation:
Let s represent sheets
Let x represent number of signatures needed
s = 25 signatures
6s + 7s = x
Plug in the function
6(25) + 7(25)
= 150 + 175
= 325
x = 325
In total she will need 325 signatures

Answer:
79°
( vertically opposite angles are equal. So, <AOB = < A'OB' )
Answer:
∠ A'OB' = 79°
Step-by-step explanation:
∠ AOC = ∠ C'OA' = 35° ( vertical angles )
BOB' is a straight angle , thus
∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°
C'OC is a straight angle, thus
∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°

Answer:
Y equals -1/5
Answer:
y = -0.2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
[tex]\frac{3.6}{0.2(6y + 1)} =\frac{9}{0.5y}[/tex]
Step 2: Solve for y
Distribute 0.2: [tex]\frac{3.6}{1.2y + 0.2} =\frac{9}{0.5y}[/tex]Cross-multiply: [tex]9(1.2y + 0.2) =3.6(0.5y)}[/tex]Distribute: [tex]10.8y + 1.8 =1.8y[/tex]Subtract 1.8y on both sides: [tex]9y + 1.8 =0[/tex]Subtract 1.8 on both sides: [tex]9y = -1.8[/tex]Divide both sides by 9: [tex]y = -0.2[/tex]Step 3: Check
Plug in y to verify it's a solution.
Substitute: [tex]\frac{3.6}{0.2(6(-0.2) + 1)} =\frac{9}{0.5(-0.2)}[/tex]Multiply: [tex]\frac{3.6}{0.2(-1.2 + 1)} =\frac{9}{-0.1}[/tex]Add: [tex]\frac{3.6}{0.2(-0.2)} =\frac{9}{-0.1}[/tex]Multiply: [tex]\frac{3.6}{-0.04} =\frac{9}{-0.1}[/tex]Divide: [tex]-90=-90[/tex]Here we see that -90 does indeed equal -90. ∴ y = -0.2 is indeed a solution of the equation.

Find the slope of the line passing through (-9,3), (-3,-5)
Answer:
-4/3
Step-by-step explanation:
Slope: (y2-y1)/(x2-x1)
(-5-3)/(-3+9) = -8/6 = -4/3
The slope is -4/3
From the given equation, list the values of A, B, and C when put into
standard form. 6y - 2x = 5
A = -2, B = 6, C =5
A = 2, B = 6, C = 5
A = 2, B = -6, C = -5
Rewriting in standard form puts the x variable before the y variable:
-2x + 6y = 5
A is the value with x, B is the value with y and c is after the equal sign.
A = -2, B =6, C= 5
q/2 - p/3 = 1/6
p/2 - q/6 = 5
X=59÷3 and y=29
Step-by-step explanation:
Days the answer
Answer:
p = 13, q = 9
Step-by-step explanation:
Given the 2 equations
[tex]\frac{q}{2}[/tex] - [tex]\frac{p}{3}[/tex] = [tex]\frac{1}{6}[/tex] ( multiply through by 6 to clear the fractions )
3q - 2p = 1 → (1)
[tex]\frac{p}{2}[/tex] - [tex]\frac{q}{6}[/tex] = 5 ( multiply through by 6 to clear the fractions )
3p - q = 30 , that is
- q + 3p = 30 → (2)
Multiplying (2) by 3 and adding to (1) eliminates the term in q
- 3q + 9p = 90 → (3)
Add (1) and (3) term by term to eliminate q
7p = 91 ( divide both sides by 7 )
p = 13
Substitute p = 13 into (2) for corresponding value of q
- q + 3(13) = 30
- q + 39 = 30 ( subtract 39 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
Thus p = 13 and q = 9
