Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer:
2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Jane and Philip working together can do a piece of work in 6 days. Jane working alone takes 5 days longer than Philip. How many days does it take Philip to do the work alone?
Step-by-step explanation:
Jane+Philip= 6 days
Jane = 5 more than P
J= 5+p
(substitute)
5+p+p=6
2p=1
Philip can do the work in 7days.
Jane= 7+5= 12 days

In an arithmetic-sudoku, the values 1,2,3,4 appear exactly once in each row and each column. Which value belongs in the grey square
Answer:
Value 5
Step-by-step explanation:
The number of rows and columns of the Sudoku is not stated; so, I will assume it is 5 by 5, since there is only one gray square left to be occupied.
If 1 - 4 appears in each row and 1 - 4 appears in each column (take for instance, the attached Sudoku image), then the value that should be entered in the gray square is 5.
If you deposit $6000 into an account paying 6% annual interest compounded
monthly, how long until there is $8000 in the account?
Answer:
It will take 4.4 years to gain $8000.
Step-by-step explanation:
Substitute the values in the formula.
A = P (1+r/n) nt 8000 = 6000 (1+0.06/12) 12t
Use BEDMAS (order of operations) and solve the value in the brackets.
8000 = 6000 (1.005) 12t
Divide both sides by 6000
1.3 = (1.005) 12t
Take the logarithm of both sides.
log (1.3) = log (1.005) 12t
Include the exponent in the equation.
log (1.3) = (12t) (log 1.005)
Divide both sides by log 1.005.
(log(1.3))/(log(1.005)) = 12t
Find out the log.
52.6039 = 12t
Divide both sides by 12.
4.4 = t

Find the measures of the angles of a triangle if the smallest angle measures 107º less than the largest angle, and the third angle is one third of the measure of the largest angle
Answer:
123°, 41° and 16°Step-by-step explanation:
x - the measure of the largest angle
x - 107° - the measure of the smallest angle
¹/₃x - the measure of the third angle
x + x - 107° + ¹/₃x = 180°
2¹/₃x = 180° + 107°
⁷/₃x = 287°
x = 287°÷⁷/₃
x = 287° · ³/₇
x = 123°
x-107° = 123° - 107° = 16°
¹/₃x = ¹/₃ · 123° = 41°
The measures of the angles of a triangle are (3x – 100)°, (x – 10)°, and (x – 10)°.
Solve for x and find the degree measurement of the largest angle in the triangle.
x =
The largest angle in the triangle is
degrees.
Answer:
x = 60
largest angle = 80°
Step-by-step explanation:
the sum of all three angles in a triangle = 180°
(3x - 100) + (x - 10) + (x - 10) = 180
simplify:
5x = 300
x = 60
angles are 80°, 50°, and 50°

Answer:
A=1089
Step-by-step explanation:
Area of a trapezoid= (big base+small base)/2 x height
A=(67+54)/2 x 18
A=60.5 x 18

Lucy wants to make different types of pie. Each pie uses 3/4 pounds of flour. She has 3 pounds of flour.
How many pies can she make
Answer: 3 -:- 3/4 = p
If you apply the rules keep change flip
You will keep 3/1 change divisions to multiplication and flip 3/4 to 4/3 so new equation 3/1 x 4/3 = 12/3 then 12÷3= 4 so your answer will be 4 pies

A random representative survey of 100 seventh-graders in Washington Middle School shows that 20 students read 5 or more books over the summer. If there are 275 seventh-graders at Washington Middle School, based on the sample results how many seventh-graders read 5 or more books last summer?
20 out of 100 read 5 or more.
20/100 = 0.2
Now multiply the total students by 0..2:
275 x 0.2 = 55
55 people read 5 or more books.

Q' = ( -10 , 6 )
Step-by-step explanation:
P' - P = ( 18-12, -6-(-4)) = ( 6 , -2)
That is, the PQ line segment has moved 6 units to the right and 2 units to the bottom.
Q' - Q = ( 6 , -2 ) → Q' = ( 6 , -2 ) + ( -16 , 8 ) = ( -10 , 6 )
