Answer:
23
Step-by-step explanation:
Three years ago, Russel was 20 and Emma was 40. That is double, and then three years later, Russel would be 23
Answer:
Step-by-step explanation:
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
Answer:
Therefore, the groups of 1/4 in 7 are, Number of one-fourth = 7/ (1/4) = (7×4)/1 = 28 Hence, the groups of 1/4 in 7 are 28.
Step-by-step explanation:
Answer:
X=69 degree
?= 50 degree
Step-by-step explanation:
exterior angle prop so 77+X =146
X=146-77
X=69
in sencond triangle
90+40+?=180
?=180-130
?=50
Answer:
x = 15
Step-by-step explanation:
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
