<span><span>1.
</span>60 is 10
times as much as is what value?</span>
<span><span>2.
</span>60 is 1/10
of what value?</span>
To interpret these given
problems we can first analyse these given word problems to a mathematical expression.
Hence the given becomes then;
Let N be the unknown value.
<span><span>
1.
</span>10 x N = 60</span>
<span><span>2.
</span>N / 10 = 60</span>
To solve these equations we
just have to find the unknown or N.
<span><span>
1.
</span>10N = 60</span>
<span><span>a.
</span>N = 60/10</span>
<span><span>b.
</span>N = 6</span>
<span><span>
c.
</span>10 x 6 = 60</span>
<span><span>2.
</span>N / 10 = 60</span>
<span><span>
a.
</span>N = 60 x 10</span>
<span><span>b.
</span>N = 600</span>
<span><span>c.
</span>600 / 10 =
60</span>
C) meters because 10 millimeters makes 1 centimeter, 10 centimeters makes 1 decimeter and 10 decimeter makes 1 meter (39.37 inches)
Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
Answer:
45in³
Step-by-step explanation:
6 x 5 x 3 = 90/2 = 45in³
Sqrt(49)*sqrt (-1) -4 = 7i-4
