<u>Answer:</u>
- The cost of 1 dozen doughnut is $6 and the cost of a dozen croissant is $10.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- D = Cost of a dozen doughnut
- C = Cost of a dozen croissant
- 10D + 7C = 130
- 6D + 4C = 76
<u>Work:</u>
6D + 4C = 76
7(6D + 4C = 76)
42D + 28C = 532
- 40D - 42D = 520 - 532
- => -2D = -12
- => 2D = 12
- => D = 6
<u>Now, let's substitute the value of D into the first equation.</u>
- 10D + 7C = 130
- => 10(6) + 7C = 130
- => 60 + 7C = 130
- => 7C = 70
- => C = 10
Hence,<u> the cost of 1 dozen doughnut is $6 and the cost of a dozen croissant is $10.</u>
Hoped this helped.

This is my first time on this app but this question doesn’t look to hard i’m ok at math but not that good at showing my work
Isosceles triangles have to equal sides
and each side is 5 cm greater than the base
you know the perimeter is 46
i would use basic algebra
x = base
46 = 2(x +5) + x
the 2(x +5) is the equal sides
46 = 2(x+5) + x
using distributive property
46 = 2x + 10 + x
add the common variable
46 = 3x + 10
now it’s easy
3x = 46 - 10
3x = 36
x = 36 / 3
x = 12
now that we got x (base)
we know that the equal sides are 5 cm longer than the base
12 + 5 = 17
since there are 2 sides and they are equal they are both 17
so each side of the triangle would be
1. 17 cm
2. 17 cm
3. 12 cm
to check you should be able to add them all together and get 46
17 + 17 + 12 = 46
Answer:
Step-by-step explanation:
Superfiber ⇒ 5 grams ⇒ x cups
Fiber Oats ⇒ 4 grams ⇒ y cups
<u>The required inequality is:</u>
Answer: 31 ft
Step-by-step explanation: Add all of the sides together. So 5 1/3 + 5 1/3 + 10 1/6 + 10 1/6. Convert to the same denominator (6). 5+5+10+10=30. 2/6+2/6+1/6+1/6=1. And 30+1=31
