<span>What is the simplified form of the expression 7[63÷(5^2-2^2)-1]?
</span>7[63÷(5^2-2^2)-1]
= 7[63÷(25-4)-1]
= 7[63÷(21)-1]
= 7[3-1]
= 7 (2)
= 14
answer is <span>C. 14
</span><span>Which is a solution of the equation y=4x+3?
answer is
C. (4,19)
</span>y=4x + 3
19 = 4(4) +3
19 = 16 +3
19 = 19
Answer:
large jar
Step-by-step explanation:
large jar= £1.54 (divide) 440= 0.0035
small jar= £1.26 (divide) 340= 0.0037
as the large jar cost less (0.0035 > 0.0037) the large jar is the best value for money
T=PV/K
Starting with V=KT/P, multiply P on both sides to get PV=KT
Then divide K on both sides to leave T alone
And you get.....T =PV/K
the answer is 29363
Step-by-step explanation:
