Step-by-step explanation:
please help...given that elm and oak street are parallel, find m
Answer:
102°
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
m∠A = (3×38 - 12)° = 102°
Answer:
∠a = 3x -12 ( Being corresponding angle)
Now
(3x-12) + (2x + 2) = 180 ( Sum of straight angles)
5x - 10 = 180
5x = 190
x = 38
m∠a = 3x -12 = 3*38 -12 = 102

bags to hand out to students that will give them equal amounts of Chocolates and Candies. What is the Greatest Number of Bags
they can put together! Please hurry
Answer:
18
Step-by-step explanation:
54/18= 9
72/18 =12
both numbers are devisable by 3, 6, 9 or 18
the greatest number there to use is 18
Answer:
18 bags
Step-by-step explanation:
If you put 3 chocolates in 18 bags you get 54 chocolates in total. Because 3 cannot be split down any lower it will provide the maximum number of bags able to be created.
There will be 3 chocolates and 4 candies in each bag. Making it evenly split to its greatest possibility.

HELP ME ASAP IF U CAN!!! a baker needs sugar syrup that is 40% sugar how many gallons of water shoud he add to 5 gallons of 70% sugar syrup to make the 40% syrup. WILL MAKE BRAINLYEST
Answer:
15/4
Step-by-step explanation:
Equation: 40(5+x)=70*5+0x
Solve:
200+40x=350
40x=150
x = 15/4
15/4 gallons is the answer.
3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:
40% of (x + 5) = 70% of 5
0.4x + 2 = 0.7 * 5
0.4x = 1.5
x = 3.75
Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

Are the lines y=-2x-4 and 6x+3y=2 parallel? Answer Yes or No.
Yes, They are parallel
Brainliest?
Answer:
YesStep-by-step explanation:
Given lines:
y=-2x-4 and 6x+3y=2One is given in slope-intercept form, the second one in standard form
Lets bring the second one to slope-intercept form:
6x + 3y = 23y = - 6x + 23y/3 = -6x/3 + 2/3y = -2x + 2/3As we see both of the lines have the slope of -2
Since the slopes are same, the lines are parallel

Paulette’s brother gave her his DVD collection of 25 movies when he went to college. She started buying DVDs each month after that. The line-of-best fit which models the relationship between the number of DVDs Paulette has in her collection (n ) and the time since her brother went to college in months (m ) is given in the box.
n=1.8m+25
To the nearest number of DVDs, what is the approximate number of DVDs in Paulette’s collection after 14 months?
The approximate number of DVDs in Paulette’s collection after 14 months is 75 DVDs.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
let the collection of DVDs ne n and the time spend is m.
and, the Equation for the situation is
n = 1.8 m + 25
Now, the number of DVDs in collection after 14 months is
= 1.8 (14)+ 25
= 50.2
So, the total number of DVDs are
= 50 + 25
= 75
