Answer:
(-3,4)
Step-by-step explanation:
x + 2y = 5
-3 + (2*4) = 5
-3 + 8 = 5
5 = 5
2x + 3y = 6
(2*-3) + (3*4)=6
-6 + 12 = 6
6 = 6
Answer:
(-3,4)......... multiply the first equation by the coefficient of y i.e 3 (of 2nd equation)...
again multipy the 2nd eq by the coefficient of y i.e 2 (of 1st eq)
and finally solve the eq 3 and 4 ...(solve the both eq formed by multiplying)

Answer:
X= 17.5
Step-by-step explanation:
the outside of the triangle always = 180
so you need to add up all the sides and equal to 180
5x+35+x+5+2x=180
add like terms
8x+40=180
get the x alone
x=17.5

What is the degree-measure of an angle travelled by the minute hand from 3:05pm to 3:50pm?
Answer:
270°
Step-by-step explanation:
We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.
Our equation would be: 360 ÷ 12 = 30
3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.
9 · 30 = 270, so our angle is 270°

A lab technician draws a sample of blood. A cubic millimeter of the blood contains 22^3 (the 3 is an exponent) white blood cells and 22^5 (the 5 is an exponent) red blood cells. What is the ratio of white blood cells to red blood cells?
Answer:
484 : 1
Step-by-step explanation:
We can write white blood cells to:
22^5 = 22 × 22 × 22 × 22 × 22
We can write red blood cells to:
22³ = 22 × 22 × 22
Thus, white : red equals
22 (5 times) : 22 (3 times)
22² : 22^0 = 484 : 1
I hope this helps you :)
The required ratio of white blood cells to red blood cells is 1:484.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
A cubic millimeter of blood contains 22³, white blood cells, and 22⁵ red blood cells.
The ratio of white to red blood cell is given as,
Ratio = 22³/22⁵
Ratio = 1 / 484
Thus, the required ratio of white blood cells to red blood cells is 1:484.

Answer:
6 dollars i think
Step-by-step explanation:
Answer:
Gio will save about $6.
Step-by-step explanation:
You would convert 28% to a decimal which is 0.28 and then multiply 0.28 by $18.99 and you would get $5.3172 which is closest to $6 so it would be B. about $6

-0.59x+0.39x=5.8 I need help
Answer: x = -29
Step-by-step explanation:
-0.59x+0.39x=5.8
Collect like terms
-0.2x = 5.8
Divide both sides of the equation by -0.2
x = -29
Response to user in comments:
-0.59+0.39=-0.2 that is a fact
-0.2/-0.2=1 that is a fact
5.8/-0.2= - 29 that is a fact

Please answer for a and b
Answer:
a
Step-by-step explanation:
a
Answer:
Step-by-step explanation:
a can't be an integer
8/√2 doesn't reduce to an integer. It will give you 4*√2 * √2/√2 = 4√2
-√18/√2 = -√(3*3*2)/√2 = -3(√2)/√2 = -3
At best you will get 4√2 - 3
a = 4√2
b = - 3
Edit
b is correct. the answer for b = -3
a can't be done giving an integer answer. My best guess is 4 but that is not the correct answer. You could write it as (4 - 3)√2
My advice to you is to present it to your instructor and see what he/she comes up with.

An art teacher needs to cut out squares of paper for an art project from a left-over sheet of paper measuring 72 x 104 inches. What size would the biggest possible square be with sides of whole number length?
Answer:
7488 inches
Step-by-step explanation:
I think that this is the correct answer. The reason is that you have to multiply 72 x 104. I´m not 100% sure.
The required maximum area of the biggest possible square is with sides of a whole number length of 7396 inches².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
Area of the leftover sheet = 72 × 104 = 7488 inches²
area of the square = 7488
a² = 7488
a = 86.53
Somehow, for the biggest possible square to be with sides of whole number length,
The area is given as,
= 86²
= 7396 inches²
Thus, the required maximum area of the biggest possible square be with sides of whole number length 7396 inches².

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value of k?
Answer:
k=7
Step-by-step explanation:
when entering values of x in the function, it is observed that for k = 7 the results of f (x) displace 10 units. For this see the attached table. Therefore, for this case, the correct answer is k = 7 and the way to solve it is to substitute values of x in the given functions and see the results of f (x).I attach results.
You exercise 24 hours each month for a year how many hours did you exercise by the end of the year you may be able to do the math mentally thanks to expand notation and the distributive property
Please help answer with the calculation with distribution and without distribution.
Answer:
288 hours
Step-by-step explanation:
So you have 24 per month. so month can be represented by x.
24x= y
Y is the amount of hours.
One year is 12 months. so plug 12 into x
24(12) =y
y= 288
In ABC the measure of the largest angle 32 less than 3 time the smallest angle the measure of the middle angle is 8 more than half the measure of the largest angle . What is the measure of the middle angle?
Answer: The measure of the middle angle = 52°
Step-by-step explanation:
Let x = Smallest angle.
largest angle = [tex]3x-32[/tex]
Middle angle= [tex]8+\dfrac12 (3x-32)[/tex]
Sum of all angles in a triangle is 180 degrees.
So, Smallest angle+ largest angle+ Middle angle = 180°
[tex]\Rightarrow\ x+8+\dfrac12 (3x-32)+3x-32=180\\\\\Rightarrow\ 4x-24+\dfrac{3x}{2}-16=180\\\\\Rightarrow\ \dfrac{2\times4x+3x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}=220\\\\\Rightarrow\ x=\dfrac{220\times2}{11}\\\\\Rightarrow\ x= 40[/tex]
Now , Middle angle= [tex]8+\dfrac12 (3(40)-32)=8+\dfrac12 (120-32)[/tex]
[tex]=8+\dfrac12 (88)\\\\=8+44\\\\=52[/tex]
Hence, the measure of the middle angle = 52°
