Question: Help With Expressions and Equations?
write an expression to represent each of the following:
some number c subtracted from 11
a certain number d increased by 12
the product of 1/2 and y
write an equation to represent the following:
the sum of a certain number b and 7 is 14
a number p decreased by 7 is 15
one half of a number t is equal to 20
some number c subtracted from 11
a certain number d increased by 12
the product of 1/2 and y
write an equation to represent the following:
the sum of a certain number b and 7 is 14
a number p decreased by 7 is 15
one half of a number t is equal to 20
Answers:
11 - c
d+12
(1/2)y
b+7 = 14
p-7 = 15
(1/2)t = 20
c subtracted from 11 = 11-c , certain number d increased by 12 =12+d , the product of 1/2 and y = 1/2 * y , sum of a certain number b and 7 is 14 = b +7=14 , a number p decreased by 7 is 15 = 7-p =15 , one half of a number t is equal to 20 =1 1/2 *t =20 .
C-11
D+12
1/2 y
----------
B+7=14
P-7= 15
1/2t= 20
