Answer:
x = 17
Step-by-step explanation:
∠6 and ∠7 are vertically opposite angles and thus are congruent, hence
4x = 2x + 34 ( subtract 2x from both sides )
2x = 34 ( divide both sides by 2 )
x = 17
Answer:
9.3 x 8.5 = 79.05
7.6 x 2.4 = 18.24
an easier way to multiply decimals is to take away decimals and add later
example: 9.<u>3</u>x8.<u>5</u> > 93x85 = 7905 since there are two places behind the decimal add that many to the solution 7905 > 79.05

Answer:
(-1,-1)
Step-by-step explanation:
finding y
-6x + 5y = 1
+ (6x + 4y = -10)
---------------------------
9y = -9
y = -1
finding x
-6x + 5(-1) = 1
-6x - 5 = 1
+ 5 = +5
-6x = 6
x= -1
Answer:
3
Step-by-step explanation:
Pythagorean Theorem: a²+b²=c²
You can fill in the numbers you know: a²+4²=5²
(Hypotenuse must be side c)
Square those numbers and you have: a²+16=25
Subtract 16 from both sides: a²=9
Square root both sides and you get: a=3
