Answer:
The equations that are true are
B
C
E
Step-by-step explanation:
A) States that 0 + 451 = 0, but that is not true because...
0 + 451 = 451
B) States that 130 + 210 = 210 + 130, and that is true because...
130 + 210 = 210 + 130
340 = 340
C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...
(127 + 80) + 250 = 127 + (80 + 250)
127 + 80 + 250 = 127 + 80 + 250
457 = 457
D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...
(123 + 57) + 180 = 153 + (87 + 180)
123 + 57 + 180 = 153 + 87 + 180
360 = 420 (but this does not make sence)
E) States that 497 + 0 = 497, and it is true because...
497 + 0 = 497
497 = 497
Answer:
-20-15=-35
Step-by-step explanation:
I think this answers your question, sorry if I'm wrong!
Y = mx + b
slope(m) = 7
(1,8)...x = 1 and y = 8
now we sub into the formula and find b, the y int
8 = 7(1) + b
8 = 7 + b
8 - 7 = b
1 = b
so ur equation is : y = 7x + 1 <===
Answer:
79
Step-by-step explanation:
To find the value of , when x = 3, simply plug in the value of x in the expression and solve as follows:
The value of , when x = 3, is 79
Answer:
39.25
Step-by-step explanation:
Area of the shaded part= Area of the Square - Area of the Triangle
Area of the Triangle= b*h/2= 2*3/2= 3
Area of the Square= side²= (6.5)²= 42.25
Area of the shaded part= 42.25 - 3= 39.25
