£250 in the ratio 3 : 5
Answer:
Let 3x and 2x are divided into 250.
Step-by-step explanation:
3x + 2x = 250
⇒ 5x = 250
⇒ x = = 50
∴ 3x = 3 × 50 = 150 and
2x = 2 × 50 = 100
Thus, the required numbers are 150 and 100.

HELP PLZ AGAIN. Same material. It is still timed. Will give 75 pts and brainly. This is vital to my math grade. Time is on the essence and my math grade is at stake if I do not pass this. I need Slope Intercept form for the equation. HELP HELP HELP PLZ.
Answer:
m= (-9+5)/5-3
Step-by-step explanation:
I just learned this and the equation is
m=(y2-y1)/x2-x1
so good luck brotha
Answer:
b(y-intercept)=(0,1) and M(slope)=-2
Step-by-step explanation:
use the slop formula and the slope intercept form to find the slope and y intercept. slope -2. y-intercept (0,1)
with that information, the equation would be y=mx+b. y=-2x+(0,1)

Answer:
x is 103 cause it is opposite angles and y is 77 180-103 hope this helps you
Answer: x=103° y=77°
Step-by-step explanation:
Opposite angles are always the same so, as x is opposite to 103°, it would be 103° too.
To work out what y is you would have to do 180-103=77°. The reason why is because angles on a straight line always add up to 180° and you can see that 103° and y are on the same line.
Hope this helps :)

Kaylee and her friends are going into a bakery. How much would it cost to buy 1 donut and 5 cookies if each donut costs $2.00 and each cookie costs $1.25? How much would it cost to buy 11 donuts and 55 cookies if each donut cost \$d$d and each cookie cost \$c?$c?
I need the work as well
Answer:
$90.75
Step-by-step explanation:
$2 (for each donut) x 11 (the number of donuts they want
=22
Then
$1.25(for each cookie) x 55 (the number of cookie they want)
=$68.75 +$22
=90.75

Write an equation in slope intercept form for the line that passes through (-2,3) and is parallel to the graph of y=-3/4x+4
Answer:
When the equation parallel the graph then the measure of the equation is - 3/4
Then the equation is y=-3/4x+c
By using the point(-2,3)
[tex] y = \frac{ - 3}{4} x + c \\ 3 = \frac{ - 3}{4} \times - 2 + c \\ 12 = 6 + 4c \\ 4c = 6 \\ c = \frac{3}{2} [/tex]
Then the equation is
[tex]y = \frac{ - 3}{4} x + \frac{3}{2} [/tex]

Answer: 1) 8x + 2 = 90 1a. 11 2. 13x-10= 133 2a. 11
Both solve for 11.
Step-by-step explanation: 1) they’re both the same measure so they equal each other
Subtract 2 from each side 8x = 88 and x is 11
13x - 10 = 133 they’re both the same measures so they equal each other.
Add 10 to both sides because it’s already negative and 13x = 143 and you get 11
Answer:
11 for both
