4x-3y=17......(1)
5x+4y=60......(2)
Multiply equation (1) by 4 and equation (2) by 3:-
16x - 12y = 68
15x + 12y = 180
Adding these 2 equations:_
31x = 248
x = 248/31 = 8
Now substitute x = 8 in equation (1):-
4(8) - 3y = 17
32-3y = 17
-3y = -15
y = -15/-3 = 5
So solution is x=8,y=5
Answer:
4
Step-by-step explanation:
<h3>2^3= 2x2x2= 8 + 4 =12</h3><h3 /><h3>but it is 16 not 12 so 16 - 12 =4 so that should be ur awnser.</h3><h3 /><h3 /><h3 /><h3>In return can u answer the question that i just asked on my account</h3>
7. X=5
8. X=6
9. B=-3
10. G=3.4
Answer:
Rational
Step-by-step explanation:
<u>Rational numbers:</u>
Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.
<u>Irrational numbers:</u>
These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0. <u> </u>
![\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \ \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}](https://tex.z-dn.net/?f=%5Cimplies%202.89%20%3D%20%5Cdfrac%7B289%7D%7B100%7D%20%5C%20%5C%20%5Ctext%7B%5BIn%7D%20%5C%20%20%5Cfrac%7B%5Ctext%7Bp%7D%7D%7B%5Ctext%7Bq%7D%7D%20%5C%20%5Ctext%7Bform%20%28%5Ctext%7Bq%7D%7D%20%5Cneq%200%29%5D%7D)
Thus, 2.89 is a rational number.
divide 2 into 40 that gives you 20 then subtract 2 that gives you your answer
cause she only had two left
