Answer:
infinite solutions
Step-by-step explanation:
4x+4(3x+7) = 8(2x-3) +52
Distribute
4x+12x+28 = 16x-24+52
Combine like terms
16x+28 = 16x +28
Subtract 16x from each side
16x-16x+28 = 16x-16x +28
28=28
This is true, so there are infinite solutions
U would measure it with the teaspoon and the 1/6 teaspoon
you would need 2 use the 1/2 teaspoon 4 times to get 2 teaspoons and the `1/6 teaspoon 4 times to get 2/3.
1/6+1/6=2/6*2=4/6 =2/3
hope this helps
Exponent rule : a^-b = 1 / (a^b)
1/9 ^-3 =
1 / (1/9^3) =
1 / (1^3) /(9^3) =
1 / (1/729) =
1 * 729/1 =
729
ur answer is B
Given :-
To Find :-
- The expression that is equivalent to one of the choices given .
Solution :-
As we know that ,
→ (-) × (-) = (+)
→ (-) × (+) = (-)
→ (+) × (-) = (-)
→ (+) × (+) = (+)
On using these open the brackets ,
→ -1/3 - 1( -4 + 1/6 )
→ -1/3 - 1(-4) + -1(+1/6)
→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)
On using now above stated rules ,
→ -1/3 +4 -1/6
Somewhat rearrange ,
→ 4 -1/3 -1/6
Take (-) as common,
→ 4 - (1/3 +1/6)
<u>Hence Option </u><u>(</u><u>d)</u><u> </u><u>&</u><u> </u><u>(f) </u><u>are</u><u> correct .</u>
I hope this helps.
