The answer is chicken $8, duck $5
x - the cost of a chicken
y - the cost of a duck
<span>he sold 50 chickens and 30 ducks for $550: 50x + 30y = 550
</span><span>he sold 44 chickens and 36 ducks for $532: 44x + 36y = 532
</span>50x + 30y = 550 divide by 10
44x + 36y = 550 divide by 4
______________
50x/10 + 30y/10 = 550/10
44x/4 + 36y/4 = 532/4
______________
5x + 3y = 55 Multiply by (-3)
11x + 9y = 133
______________
5x * (-3) + 3y * (-3) = 55 * (-3)
11x + 9y = 133
______________
-15x - 9y = -165
11x + 9y = 133
______________
Sum up:
-4x + 0y = -32
-4x = -32
x = -32/-4
x = 8
Since 5x + 3y = 55 and x = 8, then:
5 * 8 + 3y = 55
40 + 3y = 55
3y = 55 - 40
3y = 15
y = 15/3
y = 5

</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>

90 + 8 ? What are you asking? :)
Answer:
1.6
Step-by-step explanation:
1/ 4/2+2^2
2*2=4+2=6
4/6=.6
1/.6=1.6
Answer:
54 degrees.
Step-by-step explanation:
So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).
Given this, set these values equal to each other to get the value of a.
d = a + b
2a = (a+10)+44
2a = a + 54
a = 54
The measure of the exterior angle is 54 degrees.
