Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation 
-----> equation 
Substitute equation
in equation 
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x

therefore
the answer is
Sari has
erasers
Answer:
Options a, b, c are correct.
Step-by-step explanation:
First let's see the equation that governs the statement, which is the following:

Therefore, reading options a, b, c are correct.
Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.
This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.
that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
Answer:
$96.25
Step-by-step explanation:
In the morning, this worker was in for a total of 4 hours. Since the wage is $11/hr, we have to multiply 4 by 11.
11 * 4 = 44
In the afternoon, they worked for 4 hours and 45 minutes. Now, we have to multiply 4 3/4 (which is the fraction form of 4 hours and 45 mins) by 11.
11 * 4 3/4 = 52.25
Now, to find the total pay, we add together both the morning and afternoon pays.
44 + 52.25 = 96.25
Therefore, the total pay is $96.25
I hope this helps!! Have a lovely day!! :)
Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100

Amount paid for next 50 watches = (55% of 80) * 50

Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125

Amount received by the watch maker = 5200 + 2200 + 4500
= £ 11900
Answer:
d:) 1024
Step-by-step explanation:
Evaluate (4 x^3)^2 where x = 2:
(4 x^3)^2 = (4×2^3)^2
Multiply each exponent in 4×2^3 by 2:
4^2 (2^3)^2
Multiply exponents. (2^3)^2 = 2^(3×2):
2^(3×2)×4^2
4^2 = 16:
2^(3×2)×16
3×2 = 6:
2^6×16
2^6 = (2^3)^2 = (2×2^2)^2:
(2×2^2)^2 16
2^2 = 4:
(2×4)^2 16
2×4 = 8:
8^2×16
8^2 = 64:
64×16
