Answer: The system of equations are
x + y = 10
3.75x + 2.5y = 35
Step-by-step explanation:
Let x represent the number of cupcakes that Camila bought.
Let y represent the number of brownies that Camila bought.
She bought a total of 10 cupcakes and brownies altogether. This would be expressed as
x + y = 10
Camila and her children went into a bakery and she bought $35 worth of cupcakes and brownies. Each cupcake costs $3.75 and each brownie costs $2.50. This would be expressed as
3.75x + 2.5y = 35
Answer:
slope(m)=4 and
y-intercept(c)=-5/2
Step-by-step explanation:
here,8x-2y=5
reducing it into slop intercept form we get,
2y=8x-5
or,y=8/2x+(-5/2)
or,y=4x+(-5/2)
comparing it with y=mx+c we get,
slope(m)=4 and
y-intercept (c)=-5/2
Answer:
6ft by 15ft
Step-by-step explanation:
just divide each number by two and add it to the origanal number.
Answer: X = y - yi - 7i
Y = (x + 7i)/(1 - i)
Step-by-step explanation: for the case of (X) you only need to pass the 7i to the other side with the subtraction sign (-7i), then we get this equation:
x + 7i = y − yi
X = y - yi - 7i
in the case of the (Y), first we select the common multiple.
y - yi = y(1 - i)
if we replace it in the original expression, we get the following equation:
x + 7i = y(1 - i)
after that you can pass the value (1 - i) to the other side dividing,
Y = (x + 7i)/(1 - i)
Answer:
A = 52°, a = 149.2, c = 174.3
Step-by-step explanation:
Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.
___
The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.
c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice
