They do (i think). im like 87% sure so like do what you will with that information
Her brother sent C. 490 messages.
In order to find this, we need to set it up as a proportion. Once we have done that, we can cross multiply and solve for the unknown variable.
(4/7) = (280/x) -----> Cross multiply.
4 * x = 7 * 280
4x = 1960
x = 490
Ummm We can’t solve it without the pictures
Answer:
312cm2
Step-by-step explanation:
Area of the triangles:
A =1/2bh
A=1/2(10*12) = 1/2*120=60.
There are two triangles. 60*2=120. 120 is the area of both triangles.
Area of the rectangle:
16*12=192.
120+192=312cm2
