Step-by-step explanation:
Are these terms alike or unlike: 2xy and 2xyz
Answer:
Unlike
Step-by-step explanation:
When it comes to like terms, the numbers must have the same ending variable, 2xy and 2xyz do not have the same ending variable, which seeing it, one ends with 2xy and the other with 2xyz. Therefore these terms are not the same and the answer is unlike.
Answer:
unlike
Step-by-step explanation:
this is bc 2xy does have a z while 2xyz does

two loaves of bread. Then she used the
remaining flour to make 48 muffins. How
much flour was in the bag when Maria
began?
Answer:
48 pounds
Step-by-step explanation:
A bag contains 77 coins consisting of quarters and nickels. The total value of the coins is $12.50. Write a system of equations that can be used to determine the number of quarters, x, and the number of nickels, y, in the bag. a x + y = 77 0.25x + 0.5y = 12.5 b 0.25x +0.5 y = 77 x + y = 12.5 c x + y = 77 0.25x + 0.05y = 12.5 d 0.25x + 0.05y =77 x + y = 12.5
Answer:
A
Step-by-step explanation:
because the answer needs both amounts of money and the beginning equation x + y = 77 can't have any other numbers.

Simplify 5a – (2a + 6)
Answer:
Step-by-step explanation:
Add '-2a' to each side of the equation.
5a + -2a = -6 + 2a + -2a
Combine like terms: 5a + -2a = 3a
3a = -6 + 2a + -2a
Combine like terms: 2a + -2a = 0
3a = -6 + 0
3a = -6
Divide each side by '3'.
a = -2
Simplifying
a = -2
5a -2a -6
3a -6

A recipe for a 14 blueberry calls for one cup of flour. The number of muffins that can be made varies directly with the amount of flour used. There are 3 1/2 cup of flour available. How many muffins can be made?
Answer:
49
49 muffins would be made because if you first multiply 14 by 3 you would get 42 and if half of 14 is 7 and you add that to 42 which would equal 49 and there is your answer.

The triangle represents a scale drawing that was created by using a factor of One-half.
A triangle with sides lengths of 5 inches.
Which is true of the measures of the sides of the original triangle?
Each side of the original triangle is One-half the length of each side of the scale drawing.
Each side of the original triangle is 2 times the length of each side of the scale drawing.
Each side of the original triangle is the same length as each side of the scale drawing.
Each side of the original triangle is 2 inches shorter than the scale drawing.
9514 1404 393
Answer:
(b) Each side of the original triangle is 2 times the length of each side of the scale drawing.
Step-by-step explanation:
If the smaller is 1/2 the larger, then the larger is 2 times the smaller. The original triangle's sides are 2 times those of the scale drawing.

Graph the line with the equation y=
- 1/5x + 4
Step-by-step explanation:
look at the attachment
.....
The graph of the linear equation is plotted and y = ( -1/5 )x + 4
Given data ,
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
On simplifying , we get
y = ( -1/5 )x + 4
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = -1/5
And , the y-intercept of the graph of the line is when x = 0
So , when x = 0
y = ( -1/5 ) ( 0 ) + 4
y = 4
Hence , the equation of line is y = ( -1/5 )x + 4

Match each radical expression with the equivalent exponential expression.
Radicals can be written as exponential expression as following:
[tex]\sqrt{3} = 3^{\frac{1}{2}}[/tex]
[tex]\sqrt[3]{2} = 2^{\frac{1}{3} }[/tex]
[tex]\sqrt[4]{3} = 3^{\frac{1}{4}}[/tex]
[tex]\sqrt[5]{2} = 2^{\frac{1}{5} }[/tex]
What is radical?The radical of a number is the same as the root of a number. The root can be a square root, cube root, or in general, nth root.
[tex]\sqrt[n]{x} = x^{\frac{1}{n} }[/tex]
Given radicals,
[tex]\sqrt{3} = 3^{\frac{1}{2}}[/tex]

1. Kate deposits $2,350 in an account that earns interest at a rate of 1.1%, compounded
monthly. What is her ending balance after 5 years? Round to the nearest cent.
B = P (1+5) "
P =
r =
n =
t =
Answer:
$454220
Step-by-step explanation:
Given: B = P[tex](1 + \frac{r}{n} )^{nt}[/tex]
But, B is the future amount
P is the present amount = $2350
r is the rate = 1.1%
n is the number of compounding per year = 12
t is the number of years = 5
So that;
B = 2350[tex](1+\frac{1.1}{12}) ^{12*5}[/tex]
= 2350[tex](1.0917)^{60}[/tex]
B = 2350 x 193.2852
= 454220.22
B = $454220
Thus, her ending balance after 5 years is $454220.
