Answer:
a) x = -2/3 y = -26/3 or -8 2/3
b) x = 12 y = 5
Step-by-step explanation:
a) since both equations begin with 'y =' you can set them equal to each other
4x - 6 = x - 8
3x = -2
x = -2/3
sub x value to find y:
y = 4(-2/3) - 6
= -8/3 + (-18/3)
= -26/3

Please help me I will give you an Brainly
Step-by-step explanation:
ok so its basically like addition the top + the bottom.
3x + 3y = 12
6x + 11y = 14
9x + 15y = 26
now u wat to cancel out
9x + 15y = 26
9
15y = 26 y = 1.7
9x = 26 x = 2.8
i think this is right i hopw this helps
Answer:
y= -2
x= 6
there you go

what is 0.41891891891892 to two significant figures?
Answer:
0. 42
Step-by-step explanation:
any number greater than 0 is significant if it's exactly 0 or less than 0 is not significant. since it's two significant figures you count the first two numbers greater than 0 which is 0.41 and we have 8 will is greater than 5 which will be rounded to 1 then rounded to 0.41 which makes it 0.42
I don't understand this, I have the answer but I don't know or how to explain my work.
Answer:
B
Step-by-step explanation:
0.25 = 1/4 = 5/20
0.35 = 35/100 = 7/20
5/20 + 7/20 = 12/20 = 6/10 = 3/5
Answer:
Step-by-step explanation:
so first you would do 0.25+0.35= 0.6
now put 0.6 into a fraction= 6/10 because 6 is in the 10th place then simplify 6/10=3/5 which to find that you divide each side by 2

Simplify:
√144a^2b^4
A) 12ab
B) 12a^2b^4
C) 12ab^2
D) 12b√a
Answer:
Option C
Step-by-step explanation:
[tex] \sqrt{144 {a}^{2} {b}^{4} } [/tex]can be written as[tex] \sqrt{144 \times {a}^{2} \times {b}^{4} } [/tex]
[tex] = > \sqrt{144} \times \sqrt{( {a}^{2}) } \times \sqrt{( {b}^{4}) } [/tex]
[tex] = > 12 \times {a}^{ \frac{2}{2} } \times {b}^{ \frac{4}{2} } [/tex]
[tex] = > 12a {b}^{2} [/tex]
A garden table and a bench cost S585 combined. The garden table costs S65 less than the bench. What is the cost of the bench?
Answer:
Bench costs $325
Step-by-step explanation:
Try setting up an equation
x = cost of garden table
y = cost of bench
equation 1: x + y = 585
We also know that the table costs 65 dollars less than the bench.
cost of garden table = bench - 65
or
equation 2: x = y - 65
Now just substitute equation 2 into equation 1
(y-65) + y = 585
and solve for y
2y-65 = 585
2y = 585 + 65 = 650
y = 325 = cost of bench

The sixth-grade class is competing in the school field day. There are 32 girls and 56 boys who want to participate. Each team must have the same number of girls and boys. What is the greatest number of teams that can be formed? How many boys and how many girls will be on each team?
Answer:
8 teams each team will have 4 girls and 4 boys
Step-by-step explanation:
We use GCD to solve this
the GCD of 32 and 24 = 8
8 is the greatest number of teams.
each team must have equal number of boys and girls so divided by two
8/2 = 4
4 girls and 4 boys
I have attached how to do GCD.
