Answer:
no
Step-by-step explanation:
you basically divide or multiply something.
say you divide 2 for 8:6, divide 2 by both #s. 8:6 would then have the equivalent ratio of 4:3

Subtract 3x—y—z from the sum of 3x—y + z and 2x–y —z. what is the the
coefficient of x in the result?
with step pls
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
y=s when x=3, find when x=12
Answer:
y = s * 4
Step-by-step explanation:
You multiplied 4 to 3 to obtain 12:
x = 3 ; x = 3 * 4 ; x = 12
Therefore, if you multiply 4 to x, you must do the same to the other:
y = s
y = s * 4 is your answer.

Answer:
A. 3x+2
Step-by-step explanation:
9x^2 + 12x + 4
can be factored:
(3x+2)(3x+2)
All sides of a square are the same length. The area is two of the sides multiplied together. Thus, (3x+2) must be the length of a side (all sides, actually)
3x+2
Brett paid $229 for 8 tickets to a baseball game, which includes the $13 service fee applied to every order. How much will Brett spend for 15 tickets?
Answer:
$418
Step-by-step explanation:
So first we need to find how much a single ticket will cost.
Subtract the service fee to get how much it cost for 8 tickets.
229-13=216
Then divide that number by 8 to find how much a single ticket costs.
216÷8=27
1 ticket costs $27.
Multiply that by 15 to get how much 15 tickets cost.
27×15=405
Then add back the service fee.
405+13=418

Look at the graph shown:
A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.
Which equation best represents the line? (4 points)
y = 1 over 3.x − 1
y = 3x − 1
y = 3x + 1
Answer:
y = 3x - 1
Explanation:
1)
passes y-axis means x will be 0,
when x = 0,
y = 3x − 1
y = 3(0)-1
y = -1 ................so matches with option 1.
2)
Here given in second option passes through ( 1 , 2 )
if x = 1
y = 3x − 1
y = 3(1) − 1
y = 2 ..........................so matches with option 2.
Therefore equation: y = 3x - 1 represents the current following.
Answer:
y = 3x - 1

Kayla's sandcastle was 7/12 of a foot tall and her sister's
was 1/6 of a foot tall. How much taller was Kayla's
sandcastle than her sister's?
Answer:
5/12 taller
Step-by-step explanation:
1/6 can also be represented as 2/12
Sisters: 2/12
Kayla's: 7/12
7/12 - 2/12 = 5/12
Answer:
5/12 inches taller!
Step-by-step explanation:
Kayla: 7/12 foot tall, and Sister: 2/12 or 1/6 of a foot tall.
No, not the people but the sandcastles. Take 2/12 from 7/12 and you get 5/12.

The simple interest on $1300 for 4 years at 5 percent per annum is
[tex] $260[/tex]is the answer
Explanation :-
Given :-
SI (Simple Interest) = $1300
r% (Rate) = 5%
n (Time) = 4 years
Applying it into the formula :
[tex] \frac{P×R×T}{100}[/tex]
[tex] = > \frac{1300 \times 4 \times 5}{100}[/tex]
[tex] = > 13 \times 4 \times 5[/tex]
[tex] = > $ 260[/tex]
Therefore, the Simple interest is $260
Which expressions are equivalent to the expression below?
-1/3 - (-4 + 1/6)
There are more then one answer
your choices are
A. 1/6 - 1/3 - 4
B. -1/3 + 4 + 1/6
C. -(1/3 - 1/6) +4
D. -1/3 - 1/6 + 4
E. -1/3 - (4 - 1/6)
F. 4 - (1/3 + 1/6)
Given :-
-1/3 - ( -4 + 1/6 )To Find :-
The expression that is equivalent to one of the choices given .Solution :-
As we know that ,
→ (-) × (-) = (+)
→ (-) × (+) = (-)
→ (+) × (-) = (-)
→ (+) × (+) = (+)
On using these open the brackets ,
→ -1/3 - 1( -4 + 1/6 )
→ -1/3 - 1(-4) + -1(+1/6)
→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)
On using now above stated rules ,
→ -1/3 +4 -1/6
Somewhat rearrange ,
→ 4 -1/3 -1/6
Take (-) as common,
→ 4 - (1/3 +1/6)
Hence Option (d) & (f) are correct .

The coordinates of the given vertices are ...
D(1, 1)E(4, 8)F(8, 8)Reflection across the y-axis changes the sign of the x-coordinate:
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
This means the reflected figure has coordinates ...
D(1, 1) ⇒ D'(-1, 1)
E(4, 8) ⇒ E'(-4, 8)

Answer:
100 degrees
Step-by-step explanation:
angles in a quadrilateral (4-sided shape) sum to 360 degrees
so add all the angles up together (80+75+105=260)
and then subtract it from 360 (so it's 100)
Answer:
100 degrees
Step-by-step explanation:
sum of all interior angles of a quadrilateral =360 degrees
80 + 75+ 105=260
360-260=100 degrees

a) A river on the map is 14 cm long. Calculate the actual length of the
river in Kilometres.
b) The actual distance between two towns is 765 km. Calculate the distance between these towns on the map.
*brainliest will be given if you answer both part A and B ;) *
** NO LINKS ALLOWED, IF I SEE ANY I WILL REPORT YOU!**
Answer:
Step-by-step explanation:
Given:
1cm = 85 km (on the map)
so map is
14 x 14 long or 85 x 85
Part A:
since the map is 14cm long, and the river is also 14 cm long, and each centimeter is equal to 85km, that means, =
14 x 85 = 1190km
so the river is 1190km long
Part B:
we can use just convert 765 into map cm to get answer,
sooo
765/85 = 9cm
