Simplify These: ( m - 3 ) + ( 3m - 5 ) =

( 5 + 5n ) - ( 1 - 3n ) =

6 ( 6a - 3 ) + 2(2a - 3 ) =

( 2a + 4 ) - ( 3a + 8 ) =

( 5x + 4 ) - ( 5 + 3x ) =

2 ( 8n - 2 ) + 3(6n - 8 ) =

2 ( 4b + 4 ) - 2(3b - 3.5 ) =

5 ( 2p + 1 ) - ( 11p + 12 ) =

-4 ( 3x + 3 ) - 3(-2 + 2=

Martin likes to make flower bouquets that have 3 daffodils and 4 tulips per vase. a daffodil has a mass of d grams, a tulip has a mass of t grams, and the vase has a mass of u grams. the expression 5(3d + 4t + v) describes the mass of 5 bouquets. match each amount in the situation with the expression that represents it. situation expression number of bouquets mass of one bouquet mass of the tulips in one bouquet 4t mass of the daffodils in one bouquet 3d + 4t + v

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o
