Solve the system.
4x + 3y = 10
9x - 4y= 1
After solving the given equations, the value obtained for x and y will be equal to (1, 2).
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given equations in the question,
4x + 3y = 10 (i)
9x - 4y = 1 (ii)
Multiply equation (i) by 9 and multiply equation (ii) by 4
36x + 27y = 90
36x - 16y = 4
A similar term of x will cancel out from here.
y = 86/43
y = 2
Put y = 2 in equation (i)
4x + 3(2) = 10
4x = 4
x = 1

well you use pythagorean theorem
12 × 3
=36
16 × 3
=48
pythagorean theorem states that:
a²+b²=c²
so
48² + 36² =3600
then, because c is squared, you just square root it
√3600 = 60

N a survey, 75% of respondents said that they watch TV for one hour each day. If 30 respondents said they watch TV for one hour each day, how many respondents took the survey in total? A 70
Answer:
40 respondents
Step-by-step explanation:
Percentage of respondents who watch TV for one hour each day = 75%
Number of respondents who watch TV for one hour each day = 30
Let [tex]x[/tex] denotes total of respondents who watch TV for one hour each day.
Therefore,
[tex]\frac{75}{100}x=30\\\\x=\frac{100}{75}(30)=40[/tex]

hope it's helpful ❤❤❤
THANK YOU.
Answer:
2x² - 8
Step-by-step explanation:
Given
(x - 2)(2x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 4) - 2(2x + 4) ← distribute both parenthesis
= 2x² + 4x - 4x - 8 ← collect like terms
= 2x² - 8
A drink is mixed in the ratio lemonade : orange : cranberry = 6 : 3 : 2 What fraction is orange?
Answer:
3/11
Step-by-step explanation:
If we add all the numbers together we get 11.
6 + 3 + 2 = 11
Therefore there are 11 parts altogether in the drink.
Orange is 3 parts out of all, so that means it is 3/11 in fraction-form.
