Which property would allow you to use mental computation to simplify the problem 27 + 15 + 3 + 5? additive identity additive inv
Fofino [41]

Answer:

Commutative Property

Step-by-step explanation:

Additive Identity: If you add a real number to zero or add zero to a real number, then you get the same real number back.

Additive Inverse: When you add the same number but reversed sign, you get 0.

Commutative Property: a + b = b + a

Addition distributive property: a(b+ c) = ab + ac.

In this case, we use the commutative property:

27 + 15 + 3 + 5 = 27 + 3 + 15 + 5.

We know that 27 + 3 = 30 and 15 + 5 = 20, so we get 50 quickly using mental math.

Complete this conversion. given: 10 mm = 1 cm given: 100 cm = 1 m find: 7.5 m = ___ mm
krek1111 [17]
We have that
10 mm is equal to -------> 1 cm----> multiply by 100
10*100 mm is equal to -------> 1*100 cm
1000 mm is equal to -------> 100 cm
and
we know that
100 cm is equal to-------> 1 m
therefore
1000 mm is equal to -------> 100 cm
100 cm is equal to-------> 1 m

1000 mm is equal to--------> 1 m
  X mm-----------------> 7.5 m
x-7.5*1000-----> x=7500 mm

the answer is
7500 mm

Parallel to y=−3/4x, through (4, -1)
kolbaska11 [484]

Answer:

y=-\frac{3}{4}x+2

Step-by-step explanation:

The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.

Slope of given line= -\frac{3}{4}

Parallel lines have the same slope. Thus, the slope of the line would also be -\frac{3}{4}.

y=-\frac{3}{4}x +c

The value of c can be found by substituting a pair of coordinates.

When x= 4, y= -1,

-1=-\frac{3}{4} (4)+c

-1= -3 +c

<em>Add 3 to both sides:</em>

c= -1 +3

c= 2

Thus, the equation of the line is \bf{y=-\frac{3}{4}x+2.
